First one looked great, but didn't have much in the way of gameplay. It's basically like... Shoot an unending gang of bad guys, collect orbs, jump a bit higher, collect more orbs, shoot more guys, collect more orbs... There's hardly time to enjoy the surroundings or any other type of gameplay because you're always being shot at by people a mile away.
You can't kill civilians, but they want you to drive around the city and hit checkpoints as fast as possible. So don't run them over, otherwise you're negating the orbs you're going to get at the end of the race...
Fun.
It's boring and pointless. I know this because I recently bought it for a few bucks and have been playing it for a few days. I love the graphics and the semi-cell shading though... I'm sure the second one will be what the first one should have been.
