Last weekend’s Operation Goliath on Mass Effect 3 had gamers join forces to fight off the dreaded Reapers. Turns out over 3 million of those bastards were killed and they have been forced to retreat.

As a reward for everyone’s efforts, the BioWare is inviting players to participate in the N7 Bounty Weekend by taking advantage of Operation Fortress between 5 p.m. PT on March 23 through 5 a.m. PT on March 26.

Gamers who partake in the action will net 25% bonus XP that applies to:

• All enemies
• All maps
• All challenge levels
• All platforms
• All weekend

To participate, all you need to do is play Mass Effect 3 multiplayer during the listed time period. The bonus applies to all XP earned.
