To access a map, type “ENGAGE XY” when playing the game, where X is stands for the episode and Y for the map. If you want to e.g. warp to E2M4, type “ENGAGE 24”.
Each episode starts with the first map (ExM1) and ends with the 8th map (ExM8). The 9th map (ExM9) is always a secret map. The map names in italics refer to those maps from which you can access the secret level of the given episode.
