The Killing Floor 2.5 map is by kicker but is revised. It can be played on KF2.51 also. Mahloeeh (DnM)changed not a few things to help gamer to complete gameplay. Revision is extensive. But the game can be played to completion by a single player. P.S. Revised it again - 03/23/2010. Changed zombie spawns at hospital with panel trigger.
The revised KF2.5 map but can be played on KF2.51 (patched). It is compressed so just uncompress and copy/paste to the subdirectory KF-Mod20. And play the map (til you drop). P.S. Please read this important message - Dottie33.freewebpages.org. P.S.S. Made changes again in this revised map - 03/23/2010. Changed zombie spawns at hospital with panels "use triggers". Added trader volume on traders at hospital. And train can go back despite time exipiration.
NOTE: This is revised extensively from the original. The zombies spawns are lessened to enable singleplayer mode gameplay. And player is allowed to finish the game despite extended time limit. Train rail gate can be opened by pressing enter button. Then gate to elevator is activated by switch on right side. Enter teleporter to hospital (last section of map) through hall opposite the winged horse (see picture above)! You can finish the map but you'll not survive! RIP!
