Valve has just announced a new 'Jungle Inferno' update for Team Fortress 2, with the highlight being a brand new map. Dubbed 'Mercenary Park', it's a "new jungle-themed disease-ridden three-control point map" created by Valve.
The video below doesn't really show much of the map, it being a new animated short providing some narrative colour to the proceedings. But the map isn't all there is: there are a handful of community-created maps as well, all jungle-themed, and for modes including Attack / Defend and King of the Hill.
This is all just the "Day 1" content – expect more stuff to roll out or be announced over the coming days.
