Mass Effect 3 multiplayer DLC may have been leaked. An image, allegedly taken from the Mass Effect 3 developer server, popped up on reddit showing new playable character classes and was then posted to Facebook. I'm hardly a photoshop expert so I can't comment on the image. I am a DLC expert and I think it's pretty obvious that ME3's multiplayer DLC will offer more character classes.
If we pretend the above image is legit, and confirmed by BioWare (which it's not) then ME3's multiplayer will soon have a Geth Engineer and Infiltrator, Batarian Soldier and Sentinel, Krogan Battlemaster and Asari Justicar.
While I personally won't be returning to multiplayer anytime soon, the Asari Justicar would be awesome to play as. I wonder if I'd get unnecessarily low cut armor? Cleavage helps serve justice.
