Im in love with oldschool fps. I got working and installed in MDB:
Magic Carpet 2
Rise of the triad
All of them with mouselook profile , if I recall correctly. Any other that you recommend? ( I got Doom 1/2/Ultimate and Brutal doom, Hexen, Heretic and strife on Delta Touch too ).
I had Descent 2 but I think I could not make a good controler layout so I dropped it, and anything older than Doom does not interest me much ( Wolf 3d, Blake Stone, etc etc )
