Just want to say - AWESOME SCENARIO!!!!. Been a Marathon gamer since my MAC days (now on Linux) back in the early 90's and I have to say this is one of the best scenarios I have ever played!
A 35-level single player major conversion.
This scenario is difficult and action-packed; it features a full arsenal of new, powerful weapons, and more threatening enemies than you could ever want.
1.4 has new Lua features like a performance overlay, weapon buffs, a lot of little bug fixes; it also applies ammo capacity limits on Total Carnage. Requires Aleph One 1.5 or newer, probably!
