Upgrade: Imposter
Quick summary
An upgrade that would make a player visually appear as though they were apart of the opposing team.
Why it would be valuable
It would be an interesting tacticle choice, to infiltrate an enemy zone without raising suspicion because you look like the enemy team.
Proposal
When a player buys this upgrade they would have the colour of their head changed to that of the opposing team. The face colour should probably remain as the orignal colour when viewed by team members, with some kind of indicator sprite showing that they are currently being an imposter. The hair style and name could also be changed to a randomly selected member of the opposing team to be extra convincing. Bullets should probably remain the orignal colour as well as kill and not kill the right teams. Otherwise it would just be super confusing. Zone crystals should probably react to you according to your oringal team colour as well. It's just a warpaint visual change, not effecting all of the other systems of the game. The upgrade would be timed. You would appear as your original colour on the minimap.
