this is the original ka_knife from knife servers, simple and clean, from the very minimum a map from 2008 or earlier - some other ka_knife has been uploaded and this one was almost lost to time according to my searches until i found it running on a knife maps server luckily, uploaded for posterity - renamed to ka_knife_original to circumvent the other map. cheers

Автор исходной карты: Lom3r and GodLike
Автор изменений: KRYSIS
Исправил толпу ошибок первоначального автора
Заблокировал возможность с помощью подсадок вылезти за карту
Полностью изменил ящики на респах ТТ и КТ, теперь на них можно залезть без подсадок
Немножко оживил воду, теперь она двигается
Сделал воду немного мутной, ибо не айс (как по мне) когда под водой всю карту видишь.

zm_toxic_z_fix2
by FIXXOR
32 slots
An updated version of zm_toxic_z_fix with further improved hideouts for humans. Playing it on CS-DREAM.SU has revealed that still only a few positions excel at holding zombies off so I decided to have another go at it. Also fixed weather not working on the map for servers which use plugins to add either rain or snow.
...
This is a remake of zm_toxichouse_zg, made by Markoffka for the ZombieGround.ru community, also known by its alias: zm_toxic_z.
Toxic Z is the only toxic house version I've ever enjoyed playing but even so most of the action happens in the courtyard and humans prefer to stay on the roof or inside the greenhouse.
The purpose of this fix is to make in-door spots more appealing while providing more ways for zombies to assault well entrenched positions. First thing I did was to allow access to the roof from inside of the house. Second thing was to allow zombies to respawn in more places so humans no longer know where to expect them to come from.
Just with these 2 changes, the map felt much improved to me but I kept going, altered more stuff and added some new spots, extending the use of shoot-through glass and bringing back some elements from NaVy's original versions of toxic house as well. I hope the result will end up being to people's liking!
Good luck at killing zombies!!!
Main changes:
- Reworked many of the bases that didn't see play.
- Redistributed spawns to improve spawn location variety and allow respawns in multiple areas of the map for deathmatch purposes.
- Added weapons pickups throughout the map.
- Added a secret teleport in the toxic waste room.
- Added a fake wall in an unlikely place.
- Added access from the tent into the greenhouse and vice versa through a hole in the grass at the very back of the tent.
- Added access to the roof from inside the house and vice versa through a ladder located on the up(...)
