This. I enjoyed Portal 2 but it's 2/3 of a game for me. Ironically I enjoy multiplayer in MMOs, but can't stand it in singleplayer series.forsinain42 said:Please don't go "Portal 2" with it and turn the single player into a tutorial for the co-op.
Also, Mass Effect is a story driven singleplayer series - and if there's one word of plot locked behind a co-op or nothing mode ala Portal 2 the resulting rage wil be entirely justified. It's bad enough that they expect us to buy DLC to get the full story, but forcing us to tolerate some half assed multiplayer gimmick for extra story... no thank you.
Hopefully this will be just be a system whereby other players can control squadmates during the combat. That would take away absolutely nothing from the singleplayer whilst providing something extra for the multiplayer fans - co-op combat on the hardest difficulty could actually be quite interesting.
