Valve has announced a "massive" update for its free-to-play first-person shooter Team Fortress 2, called Pyromania.
The update, to be spread across three days, goes live today with the launch of Doomsday, a new map with a new game mode.
In Valve's words: "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."
Included are achievements, which you can see on the official Doomsday website.
Meanwhile, the long-awaited Meet the Pyro - the final Meet the Team short - premiers this Wednesday, 27th June.
"Keep your eyes open, folk," Valve said. "We'll be announcing a bunch of new stuff this week, right up until the premiere of Meet the Pyro this Wednesday."
