Team Fortress 2, and now the studio has revealed "Rottenburg", home of the insane German medic.
"The second of our Two Cities finds the mercs defending the Medic's vaguely European hometown of Rottenburg — a sprawling village famous for its centuries-old traditions of 1) chasing the next in the resident lineage of mad doctors out of town with torches and pitchforks whenever they swapped out too many super-charged baboon hearts, and 2) never having been attacked by an army of robots," states the official page.
As with Mannhattan, Rottenburg features new Steam and Team Fortress Achievements and unlockables, as well as new weapon upgrades, including a boosted rocket launcher. The Medic himself gets new items like the Re-Animator, Mad Milk Syringe, and Projectile Shield.
