Valve are hard at work on their next Scream Fortress mode, the Halloween event they’ve held for Team Fortress 2 this past five years. To prepare you for the “900-mile-an-hour hellride we've got planned” they’ve reactivated the past five years’ events to be played till Halloween.
“It's been a whole year since you guys played a Team Fortress Halloween map,” Valve write. “If we threw you into the 900-mile-an-hour hellride we've got planned this year without warming you up first, you'd essentially be going from an idle state of terrorlessness to a shrieking nightmare of solid 100% terror almost instantly. It would be the equivalent of going from seeing zero skeletons to seeing a thousand skeletons at once. Are your eyes deceiving you? That's when you reach up to your eyes and realize... they are also skeletons! AWOOOOO!”
Valve want to avoid making “your heart beat so fast it would blow up your ribcage” so they’re giving access to the past five years-worth of Halloween events in preparation for the release of the sixth.
To get playing you simply need to boot up TF2 and quickplay the any of the five events in the menu.
