Operation PROPHECY details below are directly from the BioWare Blog:

Date: December 21st – December 23rd

Event Description: Our successes on Earth have given us the capability to land materiel in several war zones. However, in order to conceal shipments to the resistance, each delivery needs corresponding strikes on Reaper targets to create a screening distraction. The operations to deliberately gain Reaper attention are extremely high-risk and will require increased numbers to spread thin Reaper reaction forces. For this mission, N7 commanders, wherever possible, will recruit and command supplemental volunteer units: recent graduates of our N7 program and soldiers who bring experience from other branches.

Challenge 1: Extract once on the following maps: Firebase Rio, Firebase Vancouver and Firebase London

Challenge 2: Earn 100,000 points cumulatively against Reapers

Both Challenges can be completed at any difficulty.

Reward: Players who completed both goals will be awarded with a Commendation Pack and a brand new banner titled: “Hero of the Last Days”.

BioWare Goes on Holilday:

I hope everyone has enjoyed their year and all the new additions from Retaliation. This week, we were blessed with 3 new characters, all hazard maps unlocked and 2 new store packs. This was the good news.

Though they’ve definitely deserved it, the team at BioWare is taking a break over this holiday time. Effective December 21st, BioWare offices will be closed. This means there will be no N7 Bounty Weekends for the weekends starting December 28th and January 4th. This also means there will be no balance changes during this time.

And as a personal message to everyone out there who has continued to help Lucien with this website: thank you so much and please keep contributing. Your input and builds and startegy are what helped shape this site into something spectacular. Above all, I hope you all have a Merry Christmas and a Happy New Year.

Keep playing; and any Xbox Live users out there, I may just run into you.
