No sure this is the right place to ask; let me know if not and where else to ask...
Anyway, I am looking for an old first-person-shooter (maybe 20 years old, PC), you were shooting just some kind of monsters, not humans, and the entire play was within a closed building. Gameplay was very easy, and you have to achieve some goal to get to the next level (literally the next level), in order to prevent someone lifting up with a spaceship(?).
If you have some idea, please let me know, I then can google images from the game. Thanks.
Addendum:
- I think the game has speech in it, and probably one catch-phrase is "you will never succeed"...
