10. You'll also see the return of the best stuff from previous TF birthday celebrations, including: 9. The Manno-Technology Bundle 8. The
The 15 Years Update 
"Wow! Can you let me play it now?" you ask. Dream On, Aerosmith fan. The game's not due for a week. (Joe Perry's still coding some shaders.)
It's summertime and THINGS ARE ON SALE. If only all our writers weren’t at Writer’s Camp they could tell you HOW AWESOME THIS SALE IS. If they wrote something witty about the Scout's new TOWEL you would probably say "I really want to go out right now and buy a towel for MY scout." If they said something sad and revealing about the character of the Scout's new pair of FLIP-FLOPS you would probably say "I care deeply about Flip-Flops, if only I had a pair to show my deep feelings for Flip-Flops!
7. The Über Update 
Capture a point. Shoot a guy. Walk ten feet. Think about walking ten feet and decide not to. Whatever the occasion, celebrate it with the Meet the Medic, a custom taunt that allows you to punctuate anything you do, no matter how trivial, with god rays, orchestral swells and an explosion of doves.
6. The Replay Update
Steven Spielberg. Robert Scorcese. Socrates. The guy who made those Old Spice commercials.
5. The Mounts and Blades and Hats and Fires and Hats and Swords Update
Pre-purchase the "everything explained in the title" game Mount & Blade With Fire & Sword by May 3rd and you'll receive two new TF2 hats: The Hetman's Headpiece for the Engineer, and the Janissary Ketche for the Spy, pictured above.
4. The Hatless Update 
over it. We've missed sleep, meals, and loved ones for it. We've been up countless hours perfecting it. And now, finally, we've put it aside for a few minutes to slap together this update.
3. The First-Ever Three-Way Pack Update 
Cower, peasants! Flee, terrified ronin! Crap in your ancient Japanese bamboo underpants, feudal warlords! For something approaches unlike anything you have ever seen! The Shogun Pack -- a collaboration between Team Fortress 2, the TF community, and Total War: Shogun 2 -- descends upon you like a rising sun! (But in reverse.)
2. Community Map Pack! Update 
We've been listening to our community's famished cries for content, and damn it, we decided to do something about it. Unfortunately, the button that bans everybody in the community at once doesn't seem to be working (every time we press it we just get sparks and the smell of burnt fur). So we went with our tried-and-true Plan B: an all-new map pack, featuring some community favorites including a new map from the guy behind cp_mountainlab, the winner of TF2Maps.net's Art Pass Contest.
1. From Hell Update 
"Holy crap, this is so friggin'..." [Sounds of swinging
My 2 favorite updates were Über update and the hatless update.
The Manniversary update was just one crapload of hats...really.
