I know I tested it before, I only have 2 qualms with it 1 - there's no side stepping 2- No sound
I'm not sure if you can do anything about the sound, but its neither of them presents a huge problem.
good job.
Update on the Update:
It so much better! The sounds work, and you can toggle player view!
The Spectator.lua script makes any players on yellow team able to passively watch the game without interfering. They wont be visible to the other players and will not be able to block bullets or interfere in anyway. they move using the the turn/look keys(or mouse) and the left and right triggers to move forwards and back. Just remember that all players on yellow team will spectate.
