Not a bad concept, but the execution wasn't the greatest. The animation could have been a lot better, and while the various different things outlaws can say is cool they sometimes don't fit, like the little guys acting dumb or the big guys acting crazy.
i also found the upgrades somewhat pointless, and were just a way for you to elongate the game without having the difficulty curve spike repeatedly.
If a third is made, upgrades should be less of a focus or removed completely, and I suggest you do your best to make it as cinematic as possible.
