Zombicide: Black Plague is a standalone cooperative board game that takes the zombie apocalypse into a beautiful medieval setting.
The board game packs loads of fun and supports one to six players. It brings out the relentless zombie-killing action into a new fantasy world we have not experienced before.
It features multiple fantasy races such as elves, dwarfs, humans, paladins, magicians and other straggling survivors from different walks of life.
I was not initially sure how medieval, fantasy and zombies could possibly blend together, but let me tell you that the mix works brilliantly!
The objective of Zombicide: Black Plague is to punish the evil Necromancer overlords for bringing the world to an end, but to get there you have to go through the hordes of zombies first.
To help you survive dark times, your characters can wield crossbows, make powerful swords, and cast magic spells. To improve your defense rating, you can arm your survivor with shields and chain mail armor. Additionally, you can pick up spell books to carry out fantastic enchantments, or light up a dragon pool to come up with an all-consuming dragon fire!
While the rules have been slightly revamped for this latest incarnation, the core principle has remained intact. The board game is still full of nonstop action, tense atmosphere and loads of fun!
The game incorporates some of the light RPG mechanics as it allows you to enhance your character and gain experience as you go. Experience allows you to up-skill your characters to become more powerful, however, the increased number of zombies over time seems to balance it out nicely.
Go ahead and take on the zombie invasion from secret vaults to medieval streets. Pursue the elusive Necromancers to prevent them from multiplying. Take a whole new set of missions whereby your group of survivors will emerge the heroes of the land or the last survivors of the zombie massacre.

Zpocalypse 2: Defend the Burbs is a Kickstarter funded exhilarating cooperative and competitive tower defense-game. It represents a sequel to the original Zpocalypse, a survival board game that’s set in a post-apocalyptic wasteland.
The premise of the board game is pretty exciting. When the city got heavily bombarded, some humans have run for their lives to survive the onslaught by escaping to the urban wasteland. Out in the suburbs, humans have built a shelter which is now regularly raided and assaulted by zombies and mutates.
To survive, players have to rely on almost anything from kitchen appliances to garden tools to fend off the never ending zombie hordes.
During setup, you and your friends randomly select two survivors in addition to two starting weapons. The cards are then attached to a special board with each player leading one of the heroes. Depending on the color chosen, players get one pointer that marks the starting point or position on the action board. Some scenarios contain additional rules that modify the course of the game slightly.
Just like the original game, the updated version has simple and straightforward rules. The game involves two to five players each controlling their squad of survivors that is equipped with food, weapons, and other items. As a squad leader, you get to choose the actions your survivors should concentrate on. You get to select and prioritize daily tasks and other duties on the action tracking board. Each action brings value to the squad, yet costs resources, so picking and timing the right choice is paramount.
Similar to other zombie board games, Zpocalypse 2 features a concept of day and night. During the day, you get to assign your squad various actions such as scavenging, crafting, guarding and resting. The objective is to prepare for the night phase where the new zombies get spawned and assault your shelter.
As you progress through the board game, your survivors level-up and gain new skills. Each time you kill a zombie you get to score victory points which are then used to unlock perk cards. Each card can provide a noticeable enhancement by improving the defense stats, dealing extra damage or healing the wounds.
The game also introduces a nice variety of zombies, so it does not feel too mechanical fighting them. In addition to regular zombies, the game introduces mutates which have different health, attack, movement, and special abilities.
As opposed to having your scenario path determined for you like it was in the original game, now you have the freedom to decide your own survival scenario. It is a great perk, especially for someone creative like me.
|Zpocalypse 2: Defend the Burbs is an epic post-apocalyptic zombie survival game that comes with some lite RPG mechanics and story telling. It features an intriguing day and night concept allowing you to prepare during the day and fight zombies during the night. If you like tower defence type games, that can be played both cooperatively or competitively – Zpocalypse 2: Defend the Burbs might be just what you are after.|

Dawn of the Zeds (Third edition) is a third iteration of the board game classic that was funded via a Kickstarter campaign.
It remains to be a go to game for those who are looking for a solidly changeling warfare against zombies. It features a cooperative gameplay in a zombie apocalypse.
In Dawn of the Zeds your heroes need to defend Farmingdale in addition to its five outlying villages from zombies that keep on encroaching.
These heroes are often supported by armed and heroic civilians with little outside help. There are mad scientists, biker gangs, and civilians fighting for zombie rights.
The rules are fairly simple. All you have to do is to ensure that you defend the town of Farmingdale and its neighboring towns from zombies’ onslaught.
The goal is to ensure that the Zeds do not reach the town center to cause chaos around Farmingdale, a town that has been abandoned by the government.
Gameplay is simple. Found at the center of the board is a docile hamlet of Farmingdale that’s under siege from hordes of zombies that travel along four roads leading to Farmingdale. However, you must be cautious here since even if one of them succeeds to enter the town, then its game over.
The new edition has completely raised the bar as far as the sheer number of options for playing the game and the presentation is concerned. With the latest offerings Dawn of the Zeds (Third edition) still packs a lot of action and fun.
Originally, Dawn of the Zeds (Third edition) was a solitaire game but in this third edition, the gameplay is just as much as on cooperative play. Now, 1-5 courageous individuals can spend more than 90 minutes fighting zombies and learning to come together as a group to fight a common and determined enemy.
|As a fan of cooperative games, Dawn of the Zeds (Third edition) makes you want to enjoy this game time and time again. If you want to enjoy a tense, multi-player, and balanced game-play, then this is the right game for you. In fact, it’s turning out to be the bar upon which other zombie board games are measured.|

|The player aids are designed excellently|
All locations found on the game board are well-marked

Last Night On Earth is one of the most discussed classic zombie board games of all times. The game has been out for over ten years and has proven to be a favorite option for many zombie board game enthusiasts.
Now, with the 10th Anniversary edition out, the board game features welcome updates, refreshed components, and a couple of new additions.
The artwork is intentionally photographic as the game aspires to achieve a cinematic feel, which does seem to work.
Like with most zombie board games, the plot is somewhat predictable. The game pits small-town heroes against a horde of zombies.
Unlike, however, many other zombie board games, this one features a full competitive mode where some players can play as heroes that are working together to make it through the tough night or zombies that spread over the town like a plague.
In addition, each scenario has a different board layout, player starting positions and features different themes such as rescue, simple survival, or escape.
You start the board game by dividing up to six players into two teams. One team controls the zombies and the other team controls up to four heroes
Playing for zombies you get to destroy buildings, stumble about, groan, and make attempts to not only
The objective for humans varies depending on the selected scenario. You may need to rescue bystanders, kill a certain number of zombies or find the gasoline or keys so that everybody can escape. For zombies it is all about eating brains, so your objective is to find and eat those tasty humans.
To determine the course of action, the board games features an awful lot of dice-rolling. And if perhaps it was a different type of game, I would consider it excessive, for a zombie-themed board game however it feels just about right. It mimics the sudden events and turns that may happen, such as zombie appearing from nowhere, tripping, losing things and so on.
Last Night on Earth is a fast-paced brain-eating zombie experience that is designed to bring out a cinematic feel as the narrative unfolds. If you are looking for a classic zombie experience in its true sense, then this is one of the best zombie board game around. The fun, tension, and suspense is unavoidable in this truly epic zombie experience.

City of Horror is another classic zombie board game in our review. It was originally released in 2012 and still remains one of the most played zombie board games on the market.
The game uses classic zombie movies as a theme where hordes of zombies assault and overrun the city.
Like with most zombie board games, it is about survival, unlike most, it introduces the concept of backstabbing which makes it semi-cooperative.
The objective of the game is to survive until the daybreak when some additional help should arrive. While you are waiting for help negotiation, charming and backstabbing take place.
Sometimes, you may need to sacrifice some for the be the greater good of others to ensure you can make it through the night. But who would that be?
Each player controls a number of characters he or she is trying to shepherd through the zombie apocalypse. Characters, however, are unique and feature special abilities that can be used only once per game. This makes strategy so intriguing as you need to balance between when to use the ability, when to sacrifice the survivor and how does your character fit into the overall winning strategy.
Deciding the character to sacrifice is done using voting, so people with good negotiation skills will have an advantage. At the same time, the game compels you to make difficult, tough and unwanted decisions, and there is no other way around it.
The game ends at 04:00 in the morning when the rescue helicopter comes to pick up the survivors. Yet, to get on the helicopter, your characters must possess an antidote serum to prove they are not infected. Alternatively, characters remain stranded and score no points.
At heart of City of Horror are voting and negotiation. It fills the game with interaction, collaboration, and tension. Making sacrifices is part of the winning strategy, but picking the right trade-offs and knowing how to negotiate is key to success.
Lastly, 3D component quality is great and manages to deliver a thematic feel. The board features a two-sided modular layout, which coupled with random event deck should provide you with plenty of replay value. Rules are not complex and the rulebook does a good job at walking you through them which makes it accessible to a wide range of players.
City of Horror is an amazing survival-themed board game that has become a reputable classic. With loads of interaction and negotiation, the board game promises to be thrilling, riveting and entertaining and it achieves exactly that. Despite the modern competition, City of Horror still remains one of the best zombie survival board games made in the last decade.

Since Zombie 15 features real-time fighting, it requires fast-paced collaboration and decision making. Take too long and you will get overwhelmed by bloodthirsty zombies!

After the Virus is a highly-entertaining cooperative deck-building card game.
The story is driven by 15 different scenarios stitched together to provide a narrative experience.
Each scenario can be played on its own, yet if you want that extra bit of theme and story, playing them in order is the way to go.
According to the story, 90% of the population got wiped by a virus with only a handful making it through. The ones that did have transformed into murderous zombies, while the rest are left defenseless and weak searching for shelter.
It is now up to you to rescue as many as you can while preparing your arsenal of arms to hold off the brain-eating zombies.
Like most deck-building card games, in After the Virus you want your deck to host the best cards and little to no bad cards. In reality, this is not achievable, yet if you have enough quality cards in your deck to counter the zombie influx, you should be able to balance it out.
Characters are unique regarding their special abilities and cards that form the starting deck. It adds a nice flavor and a little bit of strategy variety into the gameplay.
Each round begins by drawing a total of five cards from your deck. You may draw weapons, equipment, traps, people or zombies. When you draw zombie cards, they are immediately placed in front of the player to deal with. The objective is to try and resolve all zombies that have been played with the cards you already have in your hands. Any unresolved zombies can cause injury and potentially kill you.
Disposing zombies can be done in two different ways, and the challenge is to balance them out. First, you can kill them, in which case they return to the pile of cards they came from. Alternatively, if you can only discard, they are placed into your discard deck, which pollutes your hand.
As you progress in the game, zombies become more powerful and harder to beat. This puts a great focus on building the deck with capable cards early on in the game.
Your characters can only take 2 wounds before they die, which is not a lot, especially in the second part of the game. This makes upfront planning and deck building paramount to surviving 20 rounds after which you make it through and win the game.
After the Virus is an easy zombie card game that can be enjoyed with up to three players, but is best played solo. The game is very compact and works great on the go. With only 30 cards or so, it offers great decision making, strategic variety and plenty of chuckles and giggles. If you are looking for a fairly simple deck building zombie game that you can enjoy solo and occasionally with other, After the Virus is a great zombie card game to consider.
|Easy to teach and play with non board gamers|
|Loads of action in a short amount of time|
|Can be played solo|
|No way to recover if you had a poor start|
Tiny Epic Zombies continues the trend of successful board game campaigns funded through the Kickstarter attracting 40 times of the original pledged amount.

The choices are: team vs. game controlled zombies, team vs.player controlled zombies, free for all vs. game controlled zombies, free for all vs. player controlled zombies or simply solo.
Tiny Epic Zombies takes place in a mall that’s been devastated by zombies. Lying in the middle is the courtyard that acts as your safe space; one which the zombies are attempting to attack. The courtyard is shielded by a barricade that you can slowly increase in strength as the game progresses.
The mall that surrounds the courtyard is made up of 8 double-sided tiles that are randomly placed, making each game’s layout different. While the sides have different art, the special events and abilities that you gain from the room in each store change slightly.
For humans to win, they require to complete three scenario objectives. Alternatively, for zombies, they must either kill all survivors or gain control of the Echo Ridge’s courtyard.
Playing as humans, you will find yourself always on the run scorching for weapons to fight zombies and progress towards achieving one of the objectives. Turns typically consist of three move actions and based on where you end up, additional actions may get triggered. For example, if you end up sharing a room with a zombie, you can fight it, if you end up in an adjacent room, you can shoot it.
After completing three movements, human players can search the room and find valuable items, such as weapons, to help them fight zombies. At times, you find more zombies, rather than weapons, so you never know.
Making your turns efficient and managing the zombie count is the key to winning the game. You eventually want to move and attack as efficiently as possible since the time before the supplies run out is limited.
