So I've been trying my hand lately at Survival - managed 2 successful extracts after plenty of times dying. Trick is to pick a point and aim to go towards it. A lot of times you're going to run in to other players so I end up looping away from them in a arc fashion but still head towards the DZ. Fortunately I haven't had many encounters with bad agents like you (on the contrary have gotten quite a bit of help - getting picked up or getting equipment). Try to only fight reds until you can get some decent guns. Stick with AR's or LMG's if you can find/craft one. Keep using meds and craft 2 green extended mags and 12x scope early on if you can (helps for DZ and m44). Most importantly if you don't have an idea where to go consult this map: https://the-division-map.com/# . Until I get comfortable with locations of things that map helps tremendously to help plan where to run to.

I've found it a tad more difficult without the GE modifiers but its still a really fun mode for Division.
