this is a job for me!
also, you might need a voice command add-on, so it'll be easier to warn players of a spy without standing still
It wont be exactly like TF2. There may/may not be spys. What there will be is giant robots. For classes and robots so far I have:
Sniper - Sniper Rifle (no stuff)
Pistol
Assault - Assault Rifle (no flying stuff)
Machine Pistol?
Explosives - Rocket L
Grenades
These are just rough version, yes there will be more classes, I don't have any idea for the SMG guy or whatever yet.
Maybe we will have sentrys. I am open for suggestions.
