In case anyone hasn't got some of these achievements, they're all pretty easy and the whole thing took me less than three hours from never touching Sanctum in my life and having no idea how to do it efficiently. You can do it in half that, maybe less. Basically, you need to download the free Christmas DLC and play on that map on Easy with the standard Assault machine gun, Sniper, and Freeze. Towers should include Slow, Killing Floor, Anti Air, and Vindicator. Your main tower strategy will involve Killing Floors.in the intersections, Slows immediately before them, and Vindicators at the corners near the Killing Floors. Use your assault gun almost exclusively and shoot dudes in the yellow spots as much as possible for
Giant Enemy Crab. After Wave 2, buy four anti-airs right next to the the openings where the enemies come out. After every wave, look for Christmas presents on the floor, since you need ten for
Festivus for the rest of us. Make sure that at some point, you max out one of your Slow tiles and use the Freeze's secondary fire on an enemy in it for
I Said STOP!. Then just max out two of your other towers for
599 US Dollars. Finally, load up the first map in the list (Mine) on Normal, level up your assault gun twice, and machine gun through the first wave towerless for
(See?) I've got this. If you still need a few more crits, it's more efficient to just replay the Christmas level on easy and just keep machine gunning.
