JReed2 One of the many activities in GTA V Online is called Survival Mode. Sometimes you can find a chain gun or a rocket launcher on the Survival maps. Rocket launchers and chain guns can be good weapons to use against them if you find them on the map (unless you already have them). This ranges from individual gang members with weapons or enemies in vehicles and helicopters. Survival Mode is a cooperative mission where you fight against dozens of gang enemies in 10 total waves. Make good use of cover when fighting the gang enemies in Survival. Some cover may be good temporarily, but if stayed in too long, you may be exposed from behind. For example, if your armor is only slightly damaged, then it may be better to wait until you really need the armor. There may be a point where you need to recover your health in Survival Mode so these will prove useful.
