It has a lot of Doom-like exploration for new gear and other goodies. Also a handful optional bosses which are pretty hard to beat. But the shooting revolves around basically 3 weapon types (magic types in this case): a DMR, an SMG and a shotgun. The variations thereof don't feel different enough and the feedback lacks kick, so the shooting doesn't feel very meaty. It's still solid enough, but the story is definitely what carried me through the 20ish hours of the game.
