Obviously it doesn't permanently unlock the camo for the gun, that would require modifying stats and result in a possible TAC ban. However, it modifies only the primary of the first class, eventually i'll update it to do it for secondaries.
Whether or not it's local only is unknown, but I have tested it.

Two things to notify me of:
1. If someone gets VAC'd using this (So I can rewrite/Update thread or do whatever)
