A team of up to three players can embark on this perilous expedition as one of four classes (Devastator, Technomancer, Trickster, and Pyromancer) that evolve and change as they level up. Each draws a skillset from their powers. For instance, the Technomancer is best for long range combat, being able to create organic turrets, trip mines, and missile barrages, whereas the Devastator class is the close-range tank, able to use rocks both as extra armor and as an aerial barrage.
