What was even more amazing is you could daisy chain serial ports on computers to get multiplayer Doom running. One or more of those links could even be a phone modem.

Downside is that your framerate was capped to the person with the slowest computer, and there was always that guy with the 486sx25 who got invited to play.

Or slave two copies to yours and get "side view" which was only supported for a few releases IIRC - https://doomwiki.org/wiki/Three_screen_mode

		Yes, Doom with multi-monitors! There's (at least) one video on Youtube showing it in action with 3 monitors plus a fourth one with the map: https://www.youtube.com/watch?v=q3NQQ7bPf6U#t=1798.333333
