I'm going around for the second time with the same bounty. The weapon is worth the pain. It is my second favourite exotic. Icebreaker is number on. Granades granades granades. Practice sticking players. Play only control and camp bases. Either snipe using void or toss granades. Dont try to get it all done at once. Play a couple games and then chill out doing something else. It is frustrating but it is possible. Get a couple friends if you can to act like body guards and soften the targets for you. It is a very cool gun.
