so yea i basically wanted to be a robot in mvm and some say its 'impossible with source mod' well here is a work around idea i had:
change player's skin to blue and make him have a robot sound & model
make the blue team not attack him and make red able to hurt him
he spawns at the blue team spawn going through robot/blue team clips
I really think that would be the best work around...then again I have never coded source mod so...
