First, you must have the Killing Floor Toy Master mod installed client side as it reduces the amount of time to download from the server.

Once the mod is downloaded and installed, the following files will be required for upload to your server.

common\killingfloor\Animations
KF_Puppets.ukx

common\killingfloor\KarmaData
babydollRagdoll.ka
pinwheelRagdoll.ka
VentriloquistRagdoll.ka

common\killingfloor\Maps
TOY-DevilsDollhouse.rom

common\killingfloor\Sounds
PuppetDoll_SND.uax

common\killingfloor\StaticMeshes
Puppets_SM.usx

common\killingfloor\System
KFCharPuppets.u
KFCharPuppets.ucl
KFEffectsPuppets.u
TOY-DevilsDollhouse.int
TOY-DevilsDollhouse.ucl
TOY-Playhouse.int

common\killingfloor\Textures
KF_Puppets_T.utx
KF_PuppetHUD.utx

Once the process is completed, open up your server's KillingFloor.ini file and add the following lines to the configuration file,

[KFCharPuppets.TOYMapList]
MapNum=0
Maps=TOY-DevilsDollhouse

[DefaultTOY MaplistRecord]

And you are ready to go, enjoy.

The TOY Master Game Mode/Game Type seems to have trouble coinciding with the KFMapVoteV2 mutator for some unknown reason. If either a player leaves the server with the game mode active or if the server has more than one player and they vote for a rerun after getting wiped, the server will crash.

There was a similar issue regarding that same problem when Tripwire first implemented the KFO Game Type. I will update this section as soon as more information becomes available.

Update - 27/10/2014: One temporary solution would be to rename TOY-DevilsDollhouse.rom to KFO-DevilsDollhouse.rom as explained by DMN666 [forums.tripwireinteractive.com] on the Tripwire Interactive forums.[forums.tripwireinteractive.com]
