From Tripwire Interactive Wiki
is a wave-based co-op first person shooter for 1-6 players based around shooting mutated experiments (specimens
). It is set in the United Kingdom.
In the game, up to six players must survive waves of experimental clones (often referred to as zeds) with the goal of completing all the waves. As waves are completed, the number of monsters and the difficulty of waves increases. Once all waves are completed, the players must defeat the boss and his minions in order to win the game. Between each wave players have the opportunity to visit the trader who buys and sells a large selection of weapons of varying costs.
Custom content plays a big part in the game, with hundreds of maps and many mods to choose from, ranging from simple gameplay changes to full-blown custom enemies.
