Welcome to CROSFR01

Welcome to CROSFR01 is a Single Player and Multiplayer level in the Aftershock Toolbox. This level is inspired by the Doom PWAD CROSSFIRE #1.

This level is incompatible with GLQuake and must be run in a game engine that supports software mode such as the original DOS Quake. This is due to an AllocBlock full error, suggesting that ports with higher limits in regards to memory could load this level.
