Half Life: Opposing Force
Never played it before and the movement feels a lot faster than modern games. Its a good and fun game.
Yeah growing up with that and quake 2 modern games always feels like im running in quicksand or my controls are broken.
This is why I cannot abide the Halo series. I came to them having been raised on Quake, Unreal Tournament, and Half-Life. Halo was like moving through molasses.
