No plans this weekend? Then how about dedicating your precious time to kicking some butt in Mass Effect 3 multiplayer? The N7 Bounty Weekend: Operation Mastiff started last night and continues all weekend.
There is an Allied Goal and a Personal Goal to complete this time around, with packs offered as a reward. The Allied Goal is to complete 100,000 retrieval missions, with a reward of a Victory Pack containing an N7 weapon. Complete Extraction on Silver difficulty with one squad member from the Rebellion pack classes to earn a Commendation Pack.
Operation Mastiff is going on through Monday at 4 a.m. PST, so jump in sometime in the next couple days. Earned packs will be distributed Tuesday night
