IGN.UK got a chance to get a hands-on impression of Left 4 Dead, Turtle Rock Studios’ online survival horror shooter. Here’s some info from the article:
It seems a virus has infected the majority of the game’s inhabitants, except for a few who for whatever reason are immune. Those resistant Survivors must then battle their way through gangs of Infected to safety, using a variety of guns and explosives. Up to eight players can join a server to play, with four on the Survivor side and four playing as special Infected monstrosities.
The article continues to describe the different map campaigns, the use of a “bleed out” timer when you get critically injured, and the different types of infected (hint: there’s not just regular infected, but a BOSS infected as well).
