Overnight Valve sent through word that they're kicking off a three-day celebration titled "Pyromania" to ring in a host of new game features for Team Fortress 2.

Headlining the week's activities will be the release of "Meet the Pyro" on Wednesday, the ninth and final installment in the "Meet the Team" series of TF2 video shorts. Stay tuned for more throughout the week.

You can hit up the official festivities page right here, which features a countdown to the headline event, and an option to check out what's on offer across all three. Today it's Doomsday, an all-new game mode, with seven new "Astro-chievements" to collect and the usual Valve comedy gold.

Doomsday pits BLU against RED, with only one team getting the honor of transporting a suitcase nuke full of recalled Mann Co. Australium to American monkeynaut Poopy Joe’s rocket, so he can blast off and hunt down Soviet space chimp Vladimir Bananas. It's the same spirit of competitive enterprise that stalled the moon landing by three years when Buzz Aldrin suplexed Neil Armstrong into a pile of folding chairs at Astromania '69! Both teams will attempt to get the necessary fuel up a preposterously slow-moving elevator and into Poopy Joe’s Australium-powered rocket to the stars.
