The information tallies with the information a Reddit user posted last week, which pegged the title of this DLC as Reckoning.
"The day of reckoning is nigh!" read the description. "The Reckoning Multiplayer Expansion brings six new never before seen co-op story missions to the game and new co-op gameplay modes. It provides four new maps to conquer and hazard variations of the Earth maps. It also enables reinforcement packs that offer new kits for the Salarians, Krogans, humans and Volus. In-game reinforcement packs now include three new weapons (Chakram Launcher, Blood Pack Punisher and Adas Anti-Synthetic Rifle)."
DF: So why can a Marauder roll but a multiplayer Turian can't? Delta1-9: You are fighting female turian husks. You have reach but they have flexibility.
