[PC] [2003–2010] First-person sci-fi shooter on a desert planet with drivable vehicles and a controllable biped mech
Here's everything I remember:
Name : (maybe) battleground
It was a single-player, story-driven FPS. The game took place mostly on a desert-like planet, similar to Mars. Most enemies were human soldiers, not aliens. The combat wasn't very hectic; enemies appeared in relatively small groups. You could drive futuristic rover/buggy-like vehicles in some missions. In a few locations, there were large bipedal mechs parked on the map. You could enter them whenever you reached them. When entering the mech, the camera switched to third-person. The mech could walk and shoot, but I don't remember it flying or transforming. One mission took place inside a large industrial/nuclear reactor facility. At least one weapon had a digital ammo counter displayed on the weapon itself. I vaguely remember the title containing a word like "Battle" or "Renegade", but I'm not confident about that. It was not Halo, Pariah, Breed, Chrome, Battlefield 2142, Battle Engine Aquila, Parkan II, Gene Troopers, Project Snowblind, or Command & Conquer: Renegade.
