i got bored of black ops zombies so i though i'll have a go on waw zombies which is kinda harder tbh on the first map but since there is more then likely going to be alot of waw fans here why not tell me a good stratergy/method to do so

all im doing is

(i go in the second room when i am over runned by zombies in the first) First of all i stay in the second room which has the random weapons box in it, i stay in there till i get either, browning, deployable, ray gun or flame flower (best guns in my opinion) after i have got all those i blow one of the zombies legs off with a grenade so i have enough time to repair ALL barriers to buy me some time for the next round after i have got those and repaired everything i go upstairs, (only open one way to upstairs it will help alot) and go to the corner with grenades on the wall which will help even more, now if u got both browning and deployable you shoot away if you have flame or ray you gotta be more careful, aim for there legs if you're using ray gun because it splashes.

THIS IS ON THE FIRST MAP
