What is the Max Speed Each Class can get to?

As the first and ONLY TF2 YouTuber, I have taken it upon myself to go into PAIN-STAKING (surface-level) DETAIL about the MOST IMPRESSIVE (mediocre) WEAPONS this game has to offer! Today, I go over EVERY SINGLE WEAPON THAT AFFECTS SPEED!!! (No, I didn't forget any. Don't correct me.) DISCLAIMER: No Mannpower powerups. If I see any comments about powerups or upgrades I will delete it. pls subscribe 0:00 - Intro 0:11 - Heavy 2:11 - Soldier 3:18 - Demoman 4:49 - Pyro 5:39 - Sniper 6:37 - Spy 7:17 - Medic 7:57 - Scout 8:57 - External boosts 9:14 - The maximums 11:32 - Outro
