I'm looking for awesome oldschool DOS games to play.

I currently have:
Prince of persia,
supaplex,
skyroads.

So, not a whole lot!

Also I'm looking for 1 game in particular, it's a deathmatch game that featured jumppads, I'm sure it's older than quake and had doom-like graphics.
Also the maps where big and open, and there were powerups.
The game fit on a few floppy disks I think, or maybe even on just one.

Anyway, post (link) some good DOS games :-D
