The Thermal Thruster's "Extinguish teammates" goal. You need to extinguish 30 burning teammates with the damn jetpack, the only way to do this is by taking off next to a teammate. (The jetpack emits an airblast as you take off, this is also how you blast enemies if you didn't know, despite what the description says)

However the dragons fury's afterburn is so short that it expires before you can even pull the jetpack out, and as for the other flamethrowers, well your entire team is pyro, they won't take afterburn from the others and if they do another pyro will come and airblast it off. This means you've got one insane grind on your hands.

It's worth bringing a flammable friend with you and either sitting in spawn while they cow mangle themselves, or if you wanna stay legit, follow them around the map until they burst into flames.

Also the Hot Hand, getting the triple kill with this thing can be difficult, however it turns out that dead ringers count as kills, so if anyone is struggling with that, look for a spy that's testing the new nerf.

I shot an enemy and they died

You can do a single jump for height and maybe a wallclimb. Just don't expect to pogo, or do some speedy jumps.

Look above, there's a "sprint" bind

I don't really use this website but you guys may be interested in this, it's the game manual, the actual one, not the sentry owners guide. It's even got incorrectly named weapons, and oh boy, just wait till you see the disaster that is the keybinds card.

Also, if any of you have the TF2 standalone box, send a pic of it's manual/keybinds card, I wanna see it.
