I don't think it matters what map it is.
But gamemode is importent.
You need to play on Payload (Bots, cause its fun) or Arena (Multiplayer, if you are admin)
You can choose Koth as well but i recommend Payload or Arena.

First what you want to do is select the class that fits for you!
I highly recommend these classes. (Other classes are not that fun):
- Scout (godda go fast)
- Heavy (He is now fast and harder to kill)
- Medic (I know medic sounds like boring stuff but his syringe gun shots crazy fast)
- Demoman (Grenade Launcher and Stickys dont shoot faster :C )
- Spy (Pretty hard disguising but fun)
- Solider (The funnest class to do this, I highly recommend this :D )
- Pyro (Pretty fun to play with)

These are the only classes that are fun to me.
If you disagree feel free to choose Sniper or Engineer.

Okay,
Now to become Awesome you need to enable console. (Duh)
And then you need to insert this commands in. (First go to the map not in main menu)
Input in order: (Dont be in a small space, cause you are gonna turn big)
(1) sv_cheats 1 (Enabling Cheats)
(2) addcond 34 (Critz)
(3) addcond 72 (Speed, Infinite Jumps)
(4) addcond 74 (Becoming a giant, Infinite Ammo)
(5) hurtme -1000000 (Do this command to get more health, it is spammable. Optional cause u get 2000 when u are big)
(6) firstperson (Also Optional cause you are taken to third person when you turn big)

Okay,
When inputing the commands in order you should get this:










I dont know if this works in multiplayer servers that are modded, like with perms and stuff. i just know that in bots this works.

If you want to be the only player while playing with bots.
Do:
mp_tournament 1 (Can't remember)
mp_autobalance 0
tf_bot_kick all
tf_bot_add 20 (oppisite color).

Enjoy.
