"The day of reckoning is nigh! 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)."
This was from reddit, not sure if its legit though
Co-op story missions ?? hope they do a better job than spartan ops cause that's a joke. New co-op gameplay modes ?? Yay but I hope they mean other than the above. Four new maps ?? Yay but I hope they're better than the earth maps. Earth Hazard maps ?? London - tolerable, Vancouver - barely tolerable, Rio - instant quit game. Hell, I'd much rather have a hazard condor. More Salarians ?? Yay. More Krogans ?? Meh. More Humans ?? Yay. More Volus ?? FFFFUUUUUUUUUUUUUU. Also hope they're not all recycled abilities. AND NO DECOY/DRONE/SABOTAGE/TAC SCAN. The 3 Weapons... yay for new things to unlock. Would of prefered a couple more.
All in all not bad. Shouldn't complain though since it's probably free and atleast it's something. Plus it'll extend the lifespan on MP, starting to get tired of MP, though that'll be vastly reduced if there are no new abilities.
