Spy

-Change your disguise frequently. If the enemy knows you're a spy and tell their team "shoot sniper, hes a spy!" then they won't be as ready to kill a demoman.

-Never Feign Death when someone's chasing you! If they're good, they'll just sit on you. Or build an SG on you! Only fiegn when a newbie HW is shooting at you and you don't want to die.

-Only disguise as an HW or a soldier if you either walk or tap the forward key. Spies move too fast to be HWs.

-Don't be a scount either unless you just need a disguise to get you to their base through the front lines.

-You're first priority is to report to your team about sg positions, then take them out and tell your tem, then kife snipers, then go for flag cap. Actully, you can do them in almost any order, but they are all things to make sure you do.

-When you've been found out, toss a few holo grenades before retreating.

-Walk backwards into the enemy base and maybe chuck a normal grenade in the direction of a teammate. It looks like you're retreating, not infiltrating. ~Tom
