Most of the weapons that make up your arsenal are fairly standard, including a pistol, machine gun and the ever popular rocket launcher, though most feature an added function. For instance, the shotgun comes with three barrels that can be shot simultaneously - giving you enough firepower to stop even the biggest of enemies. Exodus
side-steps the more common FPS gaff and makes sure that every weapon, even the hand axe and pistol, are useful even when you're packing a machine gun or sniper rifle.
Some levels also feature a vehicle that is a cross between a tank and a dune buggy. Driving feels a bit like driving a warthog in Halo, only with a slightly tighter feel. Based on the demo, it also seems like you'll see a whole lot of driving throughout the game.
Exodus from the Earth may not be one of the bigger names in the FPS market, but based on my time with the game, it has a good sense of where it wants to go and looks promising.
