I thought this game was awesome, with everything it had. Def recommend to people to play it. Can't wait for the next one to come out. The only flaw I saw it has was bugs.. like 3 times I got stuck, one was up against a wall, the other times it was walking right next to the dark cracks in the floor where the monsters would spawn from. But great game, just letting you know the bugs to be fixed in the future. Thx.
I also thought you did a great job on this game. I enjoy it, and added it to my favorites. Great AI, awesome vehicles and it was fun. I also think possibly adding upgrades to individual cars can be a good idea next time around but other then that awesome job.
I think the game is good. It does have some flaws, but they are minor. (Already stated in the comments too.) Just fix the flaws and make another one, cause I did like it alot. I rated it 4 out of 5.
