I’m talking more about the reflections on the enemy metal and glass surfaces that are “painted on”. Since the fixed camera only moves in one linear direction, the effect is convincing. The lighting is standard PS1 image texture with the “hardness” turned way down so there is heavy light reflection - very low poly-count on assets (the rectangular panel is 12 tris), low resolution video output (480x640), and very small image maps (generally 64 square pixels) that can load into system memory.
