Here's my edited version of Be A Zombie. I cleaned up the code a bit to my standards.
EDIT: You can now re-enable TF2-Attributes dependency and usage by going in the .sp file and setting: #define USE_TF2ATTRIBUTES false
to #define USE_TF2ATTRIBUTES true
Then compile it with compile.exe located in sourcemod/scripting.
It will generate a new .smx file in sourcemod/scripting/compiled.
There is a bug going on right now that results in the ragdoll's skin reverting back to default.
Whether the cause is the lack of TF2-Attributes or just TF2's inventory-validating in general, it is inconsistent and I can't pin it down for now.
