Bioware has just released new Mass Effect 3 multiplayer DLC for consoles and PC, and they'll be running a promotion from April 13-16 that will allow players to pick up an additional Reserves Pack, "containing one new Resurgence character." Unfortunately, PS3 players won't get the freebie, since it seems Bioware and Sony are unable to hash out the particulars of the promotion.
"We continue to work with them to find a compromise, but until then, Sony will not allow us to run the same Multiplayer Challenges on the PlayStation 3 that we run on Xbox 360 and PC," said Eduardo Vasconcellos on the official Bioware blog.
Bioware hasn't been specific about what issues Sony is having with the promotion, nor have they mentioned any type of raincheck for PS3 fans missing out on the event.
