Please help me figure out a game from my childhood. The only things that i remember are that it was a first person shooter, killing aliens/ghosts, and that there was a rollercoaster of sorts. i remember the roller coaster being indoors and having to kill aliens/ghosts along the track. I was really young so that is all i can remember. It’s been killing me for years. I believe it was a console game (ps1 or ps2).

please help !
