I have possibly started to late ... but I have made base gameplay loop (sorry for the default car ... custom are in progress!).
Still ... many things are missing. First of all models, then combat and then improving AI .... btw. I have added local multiplayer (up to 4 players) and It's preety fun (shame that I had no one to play while recording). Anyway here is vid and time to lunch blender ... keeping fingers crossed for free weekend! Hopefully I'll have time to finish this since I have many ideas for incorporating theme :D
