Gears of War 3 | Beast Mode Challenge | Wreaking Locust Vengeance Achievement

S1ippery Jim brings you a challenge game from Gears of War 3 Beast Mode. The object is to get a kill with each of the 15 different beasts available in a single game of beast mode. Will SJ kill all the puny humans before he runs out of waves? Incidentally this also unlocks the 'Wreaking Locust Vengeance' Achievement (although the achievement does not need to be done in a single game).
