The PC version of Zombie Army Trilogy will be getting a free update that adds the playable survivors of Valve’s first two co-op zombie games, Left 4 Dead and Left 4 Dead 2. All players have to do is boot up the game, install the update, and before long you’ll be mowing down Nazi zombies and grabbing pills with any of the eight characters (though I call dibs on Ellis).
If you’re wondering why the characters from the Left 4 Dead series are now fighting Nazi zombies in 1945 Germany, don’t worry: British comic book publisher 2000 AD, of Judge Dredd fame, has a free digital tie-in comic that explains everything. Finally, if all of this sounds really awesome to you and you want to give a try, the game is currently on sale on Steam right now for $15.29, which is 66 percent off it’s original price. The sale only lasts until 10:00 AM Pacific Time on Monday August 24, so time is limited.
Zombie Army Trilogy is available now for PlayStation 4, Xbox One, and PC, though this Left 4 Dead crossover is only for the PC version. Check out the trailer for the crossover below.
