Contagion isn't your average Zombie Shooter but instead takes a more realistic and different approach to the popular genre with unique characters, environments, weapons, items, and a built in system that makes every round completely unpredictable with resources, objectives, and paths ever changing. From the creator of Zombie Panic: Source Brian "Tatsur0" Comer we introduce it's spiritual successor.
Even if it is early acces it has good balanced gameplay elements for casual gamer but I would say for a better long term experience there should be more maps (maybe community maps with HammerEditor I would create one ;) ) and a mode in which if you die you can´t respawn just if somebody use a defibrillator(or something like that) so it would be somekind of a Hardcore mode.
