The second half of Team Fortress 2's Two Cities update is giving the Medic class some new tricks in co-op, including the godlike ability to bring the dead back to life and, when ubercharged, erect a protective shield for his teammates.
New for the Medic class is the Reanimator, a device that lets players piece their exploded comrades back together after they've been killed by Gray Mann's robots. The Medic will also have access to new upgrades called Mad Milk syringes that provide a heal-on-hit effect for teammates and a projectile shield that can comfortably protect his entire team. These upgrades appear to be limited to the Mann vs. Machine co-op mode, according to Team Fortress 2's latest change log.
While the Medic is getting some across the board perks to make him more appealing to play in Mann vs. Machine, the Soldier class is also getting a boost. He can be upgraded with faster-firing rockets and can stun with direct hits.
The second map added in the Two Cities update is Rottenburg, a "vaguely European" city full of twisting cobblestone streets and iconic towers.
More details about the newly launched update are available at the official Team Fortress website.
