Happy Birthday, Team Fortress

15 years ago, the Quake mod known as Team Fortress launched, and the series is now a classic in the genre. Valve is celebrating the festivities in its sequel, Team Fortress 2, with party hats, noisemakers, and health-packs and ammo-kits redesigned as birthday cake and gifts.

"Birthday mode" is also active, inserting "Happy Birthday, Team Fortress" beach balls into the levels. Oh, and the best part? The Celebration Gib turns players' exploding giblets into explosions of balloons and confetti.

This is gonna be a wild party.
