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.
