The Anacrusis

Battle for survival against endless alien hordes with your friends! From the lead for Left 4 Dead and L4D2, The Anacrusis is a 1-8 player, sci-fi first-person shooter. Experience intense 4 player co-op action or play as the aliens and stop your friends in Versus mode. Now with Steam Workshop support!

Fight Aliens Using Fantastical Weapons

Battle the alien menace using an astounding arsenal of classic sci-fi weapons. Buy yourself some time with a stasis grenade, toss a shield grenade to provide instant cover while you pop off a heal, and bring your friends back to life using the Respawner. Or throw caution to the wind and burn friend and foe alike with the laser rifle.

Play As The Aliens in PVP Versus Mode!

PVP comes to The Anacrusis! The goals are simple, Survivors need to reach the end of the level and the Aliens must keep them from their goal. Take control of the Brute, Flasher, Grabber, Gooper, and Spawner (with more special Aliens to come) and keep your friends from escaping the level. Tuned for intense co-op PVP play with teams of 2, 3, or 4 players, or take on the bots in a private match to practice playing the aliens.

Survive the Alien Infestation!

In the distant future, mighty corporations have carried humanity to the fringes of the galaxy. After expanding unfettered across tens of thousands of systems--all devoid of intelligent life--humanity has grown complacent, until disaster strikes. Work together and survive the alien hordes!

A Fight For Survival Is Just the Beginning

The first season of The Anacrusis tells the story of four unlikely survivors--Nessa, Guion, Liu, and Lance--who are unwilling combatants in the battle to defend humanity from the alien menace. Play more and unlock more of the unfolding mystery of the alien attack.

Never Fight the Same Battle Twice

In The Anacrusis, the AI Driver controls every aspect of the game. It spawns every enemy, directs each boss, and places every weapon, gadget, and health kit. No matter your skill level, you'll find the perfect level of challenge. More than that, the AI Driver creates the kinds of video game moments that you can’t wait to tell your friends about.
