Just re-bought the Orange Box off of Steam and looking forward to getting into TF2. I always hear good things but never got a chance to play it. Pointers/tips for a first timer?
Watch your back every 2 seconds, chances you have a Spy on your ass. Play Medic, it's mostly easy, when you are sure your teammate will die RUN THE FUCK OFF, Medics are too important to be dying too fast. Around corners and open space, check the ground or the wall, if you see a dot of the opposite color of your team, that's a Sniper.
I think Sniper is a pretty forward class, you just have to avoid being a load, play aggressively. And don't use your Scope for more than 5 seconds, chances you have a Spy behind you too.
Edit: And if you follow a Spy and he runs up to some stairs, he will most likely try to jump behind you and backstab you, ruin this move by turning around as you go up.
