About This File
This is a series of levels for DOOM ][ designed to be challenging for even the most experienced players. My standard of difficulty is that I should be able to complete the level on Ultra-Violence about half the times I attempt it. On level 18, my standard was that I had to be able to complete the level.
This work was begun in November 1995, and additional levels have have gradually been added. Levels are designed for single-player, Cooperative, and Multiplayer modes. Level 8 has one bug: for some reason monsters have a bad tendency to disappear in the initial stages of the level. This seems to be due to the large amount of monsters which the com- puter must maintain, for once the Arch-Viles and several other creatures are killed, the problem goes away.
