Hey there, so, me and my best friend used to play this game a long while ago (maybe around 2010-2011) and the neither me or him can remember the name of the game. But it was a browser 3d game where there were 2 teams. Green and Red. One of them was represented by the symbol of a scorpion. I think it was the green one. The other was another animal though we're not sure of which animal it was. The game in itself was rather simple. You drove armored cars around and killed zombies. The map was an open area here both of the teams had acess from their zones. There were zombies there I think. Also you could get out of the car walk around (not sure if you as the walking player had guns). There was also a garage where you could go in and upgrade your car.
Thank you for your time š
