From: Can't finish revolution

[zero]

When I was much younger, the Marathon demo came on a Zip disk we bought. It was fun at the time, even at low settings on our Centris 650, but I just couldn't get past one section of Blaspheme Quarantine. I had flipped all the switches, killed all the enemies, and the only place left to go on the level was a ledge on the outside of the main room, that I couldn't jump to. I tried maybe a dozen times to make that jump, and kept falling short. Eventually I gave up, figuring that was as far as the demo went.

Years later, I learned there was a run key

Are the rumors true that the shotgun is in the M1 demo?
