This weekend all the way until July 5th you will have the opportunity to gain 21x the normal experience in Gears of War 2. This is once again an obvious event where Epic is trying to tell it’s fans that in Gears of War 3, you will get something pretty damn cool for being rank 100 in Gears 2. For the 4th of July, you will also get 4-times the normal amount of ammunition for the Hammer of Dawn and the mortar so you can make some fireworks happen in Gears, just in case there is nothing going on around where you live.
If you want to get super detailed on how much XP you can gain here are more specific details even down to the modes:
