In keeping with the game's new engine, LSWIII features a host of new mechanics: Jedi-only abilities; lightsaber-throwing by virtue of a new reticule targeting system; and even a dual-environment system in which a player is able to switch back and forth between two simultaneously occurring complementary situations as part of a level. In single-player mode, this is done via a picture-in-picture system; if you're playing co-op, you'll be looking at a split-screen situation wherein each player tackles a different environment. Bonkers.
