A speedrun of the game Ultima Underworld (1992) by Origin Systems and Blue Sky Productions (aka Looking Glass Studios). Inspired by thecybercat's and dandandan5's speedruns, but using a different route.
Recorded using the GOG.com release (DOSBox 0.74). The final time was 17m 35s.
Now officially listed on the Speed Demos Archive site:
