Spy

_special2, buildspecial, or airstrike = Call airstrike (must be aiming at sky)

buildspecial2 = Activate hoverboard. While on hoverboard:
Aim in direction you wish to fly.
USE (E) key = halt/continue forward movement
BACK (DOWNARROW) key = put hoverboard in reverse
detspecial = destroy hoverboard
NOTE: A hoverboard costs armor to deploy and use.

Spies carry an Aqualung so that they do not drown.
Spies can overhear enemy team chatter. Chat is garbled if distant from enemy.

If the server has enabled Spy sharing, nearby teammates will be cloaked.
While cloaking teammates, the spy itself will be semi-cloaked.

Touch an inert multigun to upgrade it to a Tesla Coil.
