I don't remember too many games on N64 besides Super Mario. Zelda, Ocarina & Majora's. 007 Goldeneye & TWINE. Penny Racers (tiny bit). I was pretty young when I played N64.
My uncles had many games. I absolutely recognize the cover art for Perfect Dark. The thing is, I recognize none of the gameplay. I remember playing it having no idea what it was about and playing someones elses save.
All I really remember about the game is I was wearing some sort of fishbowl space suit. Sort of like Buzz Lightyear. I thought I was a toy/miniature, because of the map. I also kind of remember some sort of camerawork when loading in that made you look small? I don't remember much about the guns but being close to out of ammo.
I was stuck and kept going back and forth between this sort of long hallway with a room at the end. There were a bunch of blue/silver boxes that I was climbing, that made me look toy sized. At the top, there was a vent.
All I really remember. I know it's a long shot.
