Commands

Team Fortress 2 commands are really fun to mess around with but you have a 90% chance of getting kicked from the server.

Here are my favorite commands

addcond 66 - you are invisible to anyone and can still kill<you can do this as any of the 9 classes

addcond 5 - you get ubercharged without a medic, but the effect can be removed if healed by Dispenser, Medic or being killed.

ent_create item_ammopack_full - Spawns in a Full Ammo Pack where the player is aiming

ent_create item_healthkit_full - Spawns in a Full Health Kit where the player is aiming

tf_damage_multiplier_(blue/red) <Amount> - =tf_damage_multiplier_ blue <amount>
                                           tf_damage_multiplier_ red  <amount>

Most important command is sv_cheats 0/1 - turns cheats ON and OFF
