In addition to Enki’s questions, is it pixel graphics or polygons? Any cut-scenes that you can remember? Is it a side-scroller with a top-down view? Turn based or free roaming? Any mechs like gundam or mechs like battletech?
So far, we have.
Graphics: More 2D than 3D.
POV: Bird’s eye top-down view.
Game mechanic: Exit mech and enter enemy mech.
Enemy appearance: Green Multi-legged mech. Different mechs were different colors to distinguish their abilities.
Level 1: Egyptian related, Defeat enemy mech as human.
Final level: Escape exploding base with timer.
I don’t want to toot my own horn. But I was big into mech games in the 90s. Though I was poor so I didn’t play a lot of them. But I might have encountered your game.
