BioWare has two successful Mass Effect 3 multiplayer weekends under its belt, so why not go for a third? This time the game plans to reward you for promoting your multiplayer characters, along with a collective reward if enough players promote theirs during the period, in an event dubbed "Operation Raptor."

Between 5 p.m. PST on Friday, March 30, and 5 a.m. PST on Monday, April 2, promote two of your characters for a Commendation Pack. If the community collectively promotes 150,000 multiplayer characters, everyone will get a Victory Pack. The game will also be giving out 10 percent bonus XP to help you along in that goal, so it's being called a "Bounty" weekend. The prize names are the same as the first challenge weekend, so the prize will probably be a randomly selected N7 weapon.

BioWare is announcing the weekend a little early, so if you want to get a head start on preparing two characters for level 20, you can. Plus, it comes just after last weekend's 25 percent XP bonus, so as long as you didn't promote those characters, that might help. Keep in mind that promotions reset you back to zero, so if you've been keeping someone honed for a run at a Gold challenge you'll be sacrificing them for the cause.

The announcement notes that this only goes for the PC and Xbox 360 versions. "We are continuing to work with Sony to enable these types of Operations on the PlayStation 3 platform," the company states. "We appreciate your patience, and we expect an update later this week regarding Operation Raptor and the PlayStation 3."
