About the Game

  • OnSlaught puts you in the pilot seat of an unending nightmare - where an entire alien civilization wants you dead.

  • You'll face many enemies, each demanding a unique weapon and strategy to defeat similar to classic boomer shooters like DOOM.

  • Fight flesh abominations, slingshot around black holes, and destroy an army of biomechanical alien ships.

  • Almost every asteroid in OnSlaught is fully destructible.

  • Use your grappling hook to fling explosive barrels, asteroids, and space junk at you enemies alongside your 9 other weapons.

  • Your humanity has been stripped away. Only agony remains.
