Always invest in lasers and a couple of tons of dirt. Shooting someone through a mountain, or burying a tank and watching it napalm itself are extremely satisfying experiences.
No no you all have it wrong. It's the race to get shields then the defensive computer, and use heavy diggers/sandhogs on the morons who didn't buy parachutes
In school, we usually changed the config files for massive starting cash. Setting the game for simultaneous fire made it more like 10 rounds of mutually assured destruction on the first shot. Occasionally, a computer would win due to dumb luck of being on the one piece of dirt not erased from existence.
Ahh it was always fun to set all blast ranges on as large as possible, turn off the ceiling and wind, then launch a Death's Head into the stratosphere, only for it to come down and murder absolutely every tank.
