Collective Defense

In Collective Defense, the integrity of the protected object depends on the coordinated actions of all participants. You will have a tough time, because you are responsible for all 4 fighters by yourself. But there is nothing impossible, and as is known, patience and hard work will overcome everything. Set up defense right in front of the zombies' face and find the optimal time for an attack. Invite your friends to play together in online battles against zombies.
