Mighty Bomb Jack.
You were closer earlier :)
Duke Nukem 3D?
Freespace 2?
Crusader No Remorse?
Tyrian?
System Shock 1?
Black Mesa?
Fallout?
I’ll post a new image in a few hours. I did put some hints in the earlier pictures if you re-read . :)
One of the Riddick games? Chronicles of Riddick?
I feel like I know that.
Is it Descent?
I wonder if I should start dropping some more hints, is that allowed?
Oh, man, I freaking know that from somewhere. Um… something I must have played a really long time ago though, I got nothing just at the moment.
Alien Isolation?
Quake 4?
I think the red triangle in the upper right might be a mouse cursor, so it might be some kind of point and click.
It’s REALLY hard to tell what you’ve blocked out and what’s the original image. :/
Those textures are so very very 1998.
Hm. I know what my next guess is then. Damned one-guess-per-frame rule!
