A cooperative survival horror experience set in a variety of nightmarish and surreal settings. Band together with your team-mates to defeat increasingly overwhelming hordes of freakish enemies and eventually - a horrifying boss.
this is definately, BY FAR, one of the best games i have EVER played...
Freaking HUGE arsenal (over 20 weapons)
Different enemies (10 to be specific)
Zed time (slow mo)
Different diffuculties: begginner, normal, hard, sucidal and hell on earth
Seven different perks to choose from: field medic, support specialist, sharpshooter, commando, berserker, firebug and demolitions
In general: FREAKING DAMM GOOD!
Its crack. That's all I can say. What's not to love about a cooperative zombie genocide game, with a very good variety of weapons (everything from grenade launchers, to chainsaws, to automatic weapons), perks, and mutators? The game is very unforgiving though, and some of the perks are useless in harder difficulties. It's addictive, fun, hard, and you can have fun with 5 other people.
Definitely one of the better zombie FPS games I've played. If you like Nazi Zombies, you'll love this game. It's simple, stay alive and kill all of the zombies in the wave, then get to the trader to buy new guns/ammo for the next wave. The graphics are pretty good, not the best I've seen, but they are definitely better than a lot of games. The different types of zombies have unique characteristics and battle techniques that really make you think about which zombie you are fighting before you start shooting. So far, the only zombie games that I would choose to play above this one have been the Left 4 Dead and Dead Island series.
As far as cooperative horde-mode games go, this game is the apex of the FPS food chain. There's plenty of room for this game to improve balance-wise. However, over the years since the release of the game, a lot of content has been added to the game that made the experience even more richer.
As of the time of writing, the game has 61 guns to play with across 7 perk classes, 26 maps included where you can blast 10 different types of mindless mutants, each with their distinct characteristics. There are at least 5 difficulty levels to play on, Beginners for people who never played a shooter before, Normal for the greenhorns, Hard for the veterans, Suicidal for masters, and Hell on Earth for masochists.
If that is not enough to tantalize you, there is a massive library of at least 100 extra creative maps from the modding community that can be readily downloaded from servers that run them, and plenty of mods that add extra monster types, perk classes and weapons. Go get it, now!
