I got this trainer for GTA3 that allowes activating cheats with just one simple key combination. Like, in GTA3, to make all the cars explode, you have to type bangbangbang. With this trainer TAB+7 will do the same.
The key combination TAB+6 spawns a rhino tank. When holding down TAB+6, tanks spawn quick after eachother. After you spawned some tanks, hold TAB+& to let everything explode, the tanks will bow themself into the sky. After a few seconds, the all come down, creating serious havoc. So cool.
