This is an action platform game. You control S.O.P.H.I.A. that can roll, jump, and fire two different kinds of attacks at enemies. Being a tank, S.O.P.H.I.A. cannot perform some actions (such as climbing ladders), so often Jason will have to leave the tank and to fight his way through the level alone.
That scenario also serves as an illustration of the dilemma Jason is always faced with. The game constantly reminds you of the importance of never straying too far from S.O.P.H.I.A. You never forget that these are hostile environments Jason is exploring. By putting him in an extremely vulnerable state outside of S.O.P.H.I.A. and allowing him to restore his life energy inside it, the game further enhances the tank's role as a safe haven in a world of unusual and fierce creatures. Without S.O.P.H.I.A. to protect him, all Jason has to defend himself with is a little pea-shooter of a gun, and falls from severe heights can prove fatal for him. But there's no relief quite like jumping inside S.O.P.H.I.A. to turn the tables on some robot who was previously kicking your unprotected back all over the underworld. It's not unlike a beat-up Popeye reaching for that can of spinach. It's great fun.
