basically running and not standing stiill in ine single place for more than just a couple of seconds, hold grenades for about 2 seconds and throw them directly under u and keep running. always get juggernog it makes a huge diffrence to surviving running arounf the stage is really good but if u feel a lil too crowded just run around the map but not at a full trot more like a fast paced walk because if not the will come thru the middle of the stage and cut u off u can also bounce the grenades off of the ceilings and walls as u run thru the stair case and doors. num 1 rule is always wwatch your back, dont stay still too long and if u run in circles dont run too fast unless u need to juke or get out of a sticky situation.
