It was good but not great, art worked though would be better if I saw a more visible change to my equipment as it got stronger. An improvement could be is to use citizens as bonus cash, like one pedestrian gives a 0.25x upgrade to the amount of cash awarded from that point on-wards for that round... this would encourage us to kill more than just the FBI, it also will help gain more of the upgrades faster, took me a good few hours to unlock everything, and so can get repetitive when upgrades aren't always worth while. Might I also suggest possibly having an invisible line that once crossed will automatically switch the gun to shooting backwards, and so bring a bit more capability to the overall experience. I also loved the upgrades though didn't see much point in killing citizens unless it were to give me a bonus of some kind... wish there were more upgrades and some way in regaining my health other than the shield. maybe include another upgrade row, and include in it the possibility, maybe a 5% chance that a health pack would drop, another great thing would be is a drop that drops power ups or a random box that can consist of; slowing down your surroundings, increase to damage, health regenerate(stops if you get damaged or healed either to max or the amount specified), allows for a short time unlimited grenades or oil, max shield regeneration along with a special shield that must be destroyed while not hindering the player in any way like the normal shield does. or even gun mount on both sides temporarily that helps you shoot in both directions at the same time also shoots slightly or a little faster as well. Maybe just make him duel wield for a duration... this could work by having the standard gun shooting in the default direction while having the other shoot at whoever is closest to your vehicle, so if someone behind is closer then his other hand will shoot behind him. Hope these ideas might help in improving your game, I know it might not have been taken to seriously... IDK, but it's got potential to being greater or better than it already is.
