The max amount of achievements I can get by performing any one action

achievementsteam-fortress-2

As most are probably aware, Team Fortress 2 has a ton of achievements, most of which are seemingly unrelated to each other. But I've been curious about this for a long time.

If I was a new player, what is one action I could perform that would net the most amount of achievements instantly?

For example, I came up with that if I was a spy, disguised as a medic, who killed that medic (who was healing me) with a backstab while he had an Ubercharge ready and also got Revenge on him at the same time, I would get the Achievements "Dr. Nooooo", "FYI I am a Spy", "Come in from the Cold", "Identity Theft", and "Insurance Fraud", all at the same time. Is there anything else more advanced than this?

The Soldier can put together a pretty good chunk - though as you might expect, it's rather difficult to set up:

  • Be on a server where Halloween mode is on for any reason.
  • The map is Dustbowl or Gravel Pit.
  • Have a crowd of enemies:
    1. A Pyro, who:
      • Reflected one of your rockets recently, and
      • has set you on fire
    2. A Demoman,
      • Wearing a Gibus
      • and Pyrovision Goggles
      • whom you're one kill away from dominating
    3. A Sniper
      • with a Balloonicorn
      • who's dominating you
    4. A Spy, who:
      • just stabbed one of your teammates
      • is disguised as you
    5. A fifth enemy, with 270 health or less.
  • These enemies are all capping the first point during overtime.
  • These enemies have all recently damaged the Medic healing you.

Then:

  1. The Medic pops Kritz on you
  2. You fire a crit rocket
  3. The Sniper kills you
  4. Your crocket kills all of your enemies, which wins your team the game.

As a result of this action you claim:

  • Your 1000th Soldier kill
  • 500th Demoman kill
  • 79th Balloonicorn-owner kill
  • 30th point defense
  • 20th kill while on fire
  • 20th game win
  • 10th top-3 score for MVP
  • 5th revenge kill
  • 1st domination on people wearing:
    1. A Gibus
    2. Pyrovison Goggles
  • 1st time ever completing a full round on either one of Dustbowl/Gravel Pit (having now played full rounds on all of 2Fort, Dustbowl, Granary, Gravel Pit, Hydro, and cp_Well).

By doing this, you get the following achievements:

  • A Fresh Pair of Eyes
  • Backdraft Dodger
  • Costume Contest
  • Dynasty
  • Frags of our Fathers
  • Ghastly Gibus Grab
  • Hamburger Hill
  • Impenetrable Defense or Impossible Defense (depends on map)
  • Medals of Honor
  • Mutually Assured Destruction
  • Nemesis
  • Out, Damned Scot!
  • Semper Fry
  • *S*M*A*S*H*
  • The Great Deflate
  • Tri-Splatteral Damage
  • War Crime and Punishment
  • War Crime Spybunal
  • World Traveler
  • One (if not two!) of the Soldier milestone achivements

This gives you a total of 19+2.
