Platform: PlayStation 1
Genre: Arcade shooter?
Estimated years of release: 1997-1999
Graphics/art style: I think it was 3D, third-person? Not sure as I don’t recall seeing many screenshots/images from the game.
Notable characters: n/a
Notable gameplay mechanics: something to do with a timebomb/time pressure to get through levels/stages.
Other details: I don’t remember all the details, as I found it when looking through a video game shop site’s lists, but I remember it wasn’t Descent Maximum as I had that at the time.
It seemed almost like the idea was similar to the escape sequences from that but a whole game built around that time pressure.
perhaps “G-Police”? I’ve only briefly played it’s demo on pc ~around the same time as Unreal Tournament (99) had a demo. The game was also released on PS1
G-Police is fairly arcade, and iirc missions were fairly time-limited for … some reason? anyhoo, maybe screenshots might feel familiar? https://www.mobygames.com/game/1543/g-police/screenshots/
Forsaken was pretty similar to Descent.
Different platform, but it kind of reminds me of Terminal Velocity for DOS
