With the success of last weekend's Operation Goliath, where the community went above the call of duty with two million Brute kills past the goal of only one million, BioWare is giving everyone a bonus weekend called Operation Fortress.
Everyone who plays Mass Effect 3 multiplayer this Bounty Weekend between Friday, 5PM PST, and Monday, 5 AM PST, will automatically receive a +25% XP bonus. PS3 platform included! Why so soft? Because next weekend's operation will be ridiculously hard -- at least BioWare is billing it that way.
My guess is that we're going to have to complete an operation on Gold. I've only been able to take down Cerberus on that level (I got backstabbed by a Phantom on Wave 11 but the rest of my team got a partial extraction).
