Introduction

Eras Zombie Invasion is a Co-op arcade map created by Smith where you defend Europe against evolving zombies. You will choose one of the 11 countries and build up your economy and progress your era trhough upgrades. In order to win, you will need to wipe out EVERY SINGLE ONE of the zombie buildings in the map and it is not easy to do it.


Difficulties

There are currently 7 difficulties in Eras Zombie Invasion from Easy difficulty up to Ragnarok.

Easy
Best difficulty to practice on until you’re able to stand on your own two feet and reach Era 5.

Medium
Another excellent difficulty to practice on, Medium present a much higher difficulty than Easy despite small changes.

Hard
Another leap in difficulty for practice, most professional players practice on this difficulty. Hard Difficulty requires a much more active game in order to win, great for making builds on also.

Impossible
Requires good/decent border players and some good backcountry players to make it possible to win. Without filling in those requirements, it is incredibly easy to wipe on Impossible. Being able to complete Impossible repeatedly as a Border without falling means you can do Nightmare Difficulty.

Nightmare
Another major leap of difficulty, Nightmare shouldn’t be tied to Apocalypse Difficulty as it is a calm wave before the storm. Nightmare is possible on a public lobby but requires really good/top tier players in the lobby to help hold in order to win the game.

Apocalypse
Requires immense amount of effort and players willing to border while having the best players play as Greece, Egypt, Britain, Sweden, Turkey, and Germany. Without a great cohesion of teamwork and some luck, a simple mistake early game can easily put what seems to be a clear win into a quick defeat. Note: Russia will not be able to hold on their own without heavy support from back nations. If you are able to beat Apocalypse quickly without having much problems, the players are ready to challenge Ragnarok. By beating Apocalypse Difficulty as a border or being extremely active, you gain the status of Top Tier Player.

Ragnarok
For the best of the best only. This difficulty is complete and utter hell for even the Top Tier players. Events that are able to wipe countries clean far faster than any other difficulty, bosses able to take on multiple armies at once. Zombies start with stats nearly 1 era ahead of ALL players with a boss timer of 3 minutes exactly. 6 Bosses start to spawn past 30 minutes. Beating this difficulty requires knowledge and mastery of all aspects of the game. Expect the worst frame drops.
