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.
This game has a lot of potential but it doesn't live up to what it could be.
The Engine supports large campaign-style maps with awesome ai [the zombies are already better than anything i have seen in a source game so far] and story and stuff...
but the currently included maps are boring and repetitive even when playing with a friend, the missions are pressing buttons or finding something and opening a door, then escape; the hunted mode was fun for some time but it got boring after some time, just like the objective mode.
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.
