  • Odd Jobs: Tackle an onslaught of randomly generated events with just one hour to make your mark. From zone defense to supply retrieval, you’re never short of enemies to kill and objectives to complete.
  • Earn and Learn: Kill to earn experience points and unlock new abilities and classes. Heal allies, deploy turrets, launch grenades, set traps and much, much more.
  • Tactical Single-Player: Play on your own and lead a squad through a satisfying single-player campaign, and lead your squad through a wide variety of levels using The Red Solstice’s Tactical Mode, which lets you issue commands while slowing down the action.
