MAP25: Cat And Mouse (Doom 64)

MAP25: Cat And Mouse is the 25th map of Doom 64. It is the first "fun level" that can not be normally accessed through normal play and must be accessed using the features menu acquired from beating MAP32: Hectic or with a specific password. The background music is the same heard in level 2, The Terraformer and level 16, Blood Keep. In Doom 64 TC, it is accessed from MAP01: Staging Area. The map consists of one cyberdemon standing in front of you, active as soon as you start, with Nightmare Imps throwing fireballs at you from cages located throughout the entire map.

There is a trick to dealing with the cyberdemon at the start; if the player strafes to the right as fast as he can at the level's start, he/she can avoid being seen by the cyberdemon and can run around the various parts of the level as long as he does not attack (for example, shoot the Nightmare Imps); this will cause the cyberdemon to come after him.
