A lot of people think that Total Annihilation was the first game to use real 3D terrain in an RTS. They are mistaken; this game beat TA to market by a few months. This is perfectly analogous to the fact that Wing Commander was technically the first movie to use bullet time, not The Matrix.
I never cared for this game much, and it wasn’t because it was bad (it was actually pretty average). I didn’t like it because it was…kind of mean-spirited. Case in point: one side in this game has a vehicle called the Hostage Taker which scoops up enemy infantry, lobotomizes them, straps explosives onto them and lets them go, at which point they wander around mindlessly until they hit something and blow up.
Name and developer, please!
