Raze 3 should have More campaigns so people don't get tired of playing only the alien and human campaign like raze 2. raze 3 should also have more levels to play to make it more interesting. make more people to buy and use . more weapons. more abilities. to make it awesome.
I searched the web and Raze 3 does not even exist. So I'm guessing u guys knew that. Improvements? Better weps, dude. Allow usage of shooting from tanks and helicopters. Or actually shooting them down.
