Wow this post has been a while. Yes, multiplayer with this is pretty good, and I have it installed on both Windows and Linux PCs. Online servers for it are usually dead, however. You'd have to host your own with bots or get some friends in to actually play. For singleplayer Doom, I prefer using Woof! Or DSDA-Doom. For other multiplayer ports, there's ZDaemon and Zandronum.
