A new game mode is being tested. See here for details:

Two new MvM items were added:

Stripper:
Strips buffs off a target and gives them to you. (The name was too funny to pass up.)

Zombie Head:
Turns you into a zombie. You can infect other players with zombie disease by attacking them (make sure to only attack people in your level range). If they turn into zombies, they can infect other people.

Miscellaneous changes:
Starting gold is increased by 4500 to be approximately equal with starting XP.
The flag bearers now do minimal damage per hit to avoid intentional suicide or accidental death resulting in point deduction.
