All in all this should be a fantastic game. But it falls apart because it's simply too frustrating. Okay, the missions are tough. Games can be tough if that's what the designers like, although casual players looking for a light distraction won't last long with this one. But the real problem is how the toughness clashes with the game's structure.
Many missions require players to die two or three times just to figure out the lay of the land.
But the game saves only at the beginning of each act, and that often forces players to redo missions they've already completed just to get back to the one they're currently working on. This is enormously tedious. This forced replay, and the game's tendency to shunt out into a dreary ending after two or three strikes, keeps Vengeance from achieving the lofty status its graphics engine and creativity warrant. The grappling hook is what really makes this game, opening up many fun new types of missions.
