You've probably all seen Suijin by now, this is the pack of every custom asset (and MORE!) that went into it.
It contains models, textures, particles, and overlays, enough to make a complete Japanese themed map.
The pack was a collaboration between E-Arkham (who made all the good looking models in the pack) and myself. Be sure to send enormous amounts of love his way because he has done some spectacular work, so big thanks to him.
Please do not redistribute this pack. The download is located on the TF2Maps.net site and that is where I wish for it to stay.
If you use it in your map, please provide credit. Otherwise, go nuts.
