Dat Boi Treezy has a great guide, and all of his advice helped a lot. After getting this achievement last night, with quite a bit of success in my endeavors, I just wanted to add some tips that I found to be very useful in conjunction with Treezy's guide.
1. From the start after crafting your first piece of clothing, open your map and see how close you are to a helicopter crash. If you are relatively close to one, make a bee line straight for it. If you can get there first you will find some good items, that can get you started. It can be risky as there are usually 4 or so enemies there waiting, but they are red health. Worst case scenario if you die, you just started, but the risk is worth the reward. When I get to a crash first, I usually walk away with a weapon, a couple gear pieces, a med kit, food items, medicines, etc. All the stuff you find can very well be the difference between life or death in Survival. There is also always a fire barrel at the crash site, you can equip yourself safely after looting.
2. If you are more than a couple blocks away, avoid the helicopter. Most servers usually start with around 20 or so people, chances are if it will take you more than 2 or 3 minutes to get to the helicopter it will probably be looted, between the cold you face on the way there and the lack of loot, this is probably a death sentence. Instead place a marker towards the inner side of the map, as you get closer to the DZ it gets a little warmer, so getting away from the negative 30 temps should be a priority. Along the way loot everything you can, check every store, every apartment, etc. The gear, components, meds, clothing, etc. you find are going to make a huge difference.
3. When fighting enemies, always survey the situation before engaging, pulse is great in this mode with limited visibility. When you start you have just one pistol, and even on the outskirts of the map, it is fairly common to see veteran enemies. On few occasions what I thought was three red health enemies, ended up pulling a veteran or elite which resulted in a quick end to my run. The vet and elite enemies are very tough to take down on your own, or even in a group, elites being nearly impossible early on. But don't avoid a fight, if it is just a few red health enemies fight them. They quite often will drop blue armor pieces, weapons, meds, and clothing.
*Edit* has been some time since playing this mode, and am told that there are no longer veteran enemies on the outskirts, the latest patch may have changed the enemy spawns a bit, at the time of writing, seeing a veteran enemy on the outskirts was possible. If this has changed, it can help signifcantly, but still bear in mind, surveying the situation will help significantly, whether that be spotting that red that can flank you, or spotting that elite closer to the dark zone.
4. On that note, keep a close eye on your temp when fighting. It gets cold fast early on, and if you start to freeze, not only will your health constantly drop, but if you get downed, you cannot revive yourself, even with a med kit. If your temp is low going into a fight, try to warm up, or avoid it if you can. No sense spoiling what could end up being a good run.
5. Food and drink. I feel this is very often overlooked, as even when I go into a building that has been looted by another player, these are often left behind, either because that player is full, or they just don't bother, who knows, but they are critical items that go well beyond helping you have a good score at the end. Canned food and Energy bars will keep you from going hungry, but while the buff is active will allow your health to regenerate missing bars, even in a fight! sometimes having that extra energy bar has saved me from wasting a med kit. Bottled water and soda will stave off thirst, but (and quite possibly the biggest perk in the game), while the buff is active gives you the ability to see loot farther away, even through walls. Lootable containers will have an orange glow to them, that you can even see through walls. This saves you a lot of time when looting, and makes it easy to get everything quick without wasting time searching going into a looted building, I will still sometimes find items by doing a quick run through with my drink buff, because it was slightly hidden so the last player missed it. Always keep your food buffs active if you have the ability, it helps tremendously.
5.Looting dead players! Look, not everyone is going to make it out alive in survival, it is designed that way, and we have to accept that. Players are going to succumb to the cold, disease, enemies, etc. But when they die, they leave behind everything but their clothes, and all that loot can be yours! Keep an eye on your kill feed. If you see someone has left survival, that means they died. When that happens, quickly open your map and see how close you are to their red X. Like the helicopter if you are only a couple blocks away, set a marker and go straight there. If you get there first, you can get everything they had, including their crafting components. This can save you a lot of time looting, and help maximize your time in the DZ. However, be very careful. Even if the cold killed them, there is a good chance enemies are nearby to their bodies, so either be ready for a fight, or some ninja moves. Now look, I am not saying be a dick, and let people die, or don't help them fight, etc. But, it is inevitable that other Agents will die, on servers that start with 20 players, by the time I extract there are usually around 5 left, and I get first extraction bonus points, so why let their deaths be in vain? Grab their stuff! By looting one or two dead players, I usually have more crafting components than I know what to do with.
6. Learn the map layout. It may not seem this way. But all the loot is in the same place. What comes out of the containers themselves is randomized, but it is always in the same place. So if you happen by an apartment that you remember you looted last time, go back in this time. The same containers will be there. Also learn what each container always holds. Suit cases, dressers, clostes, etc. always have clothes in them. The green cases large or small will always have a gear piece (until you get to the DZ then they are sealed caches). Red back packs always have a med kit, and red duffle bags always have medicine or pain killers. The brown back packs always have either a food item or clothing. Division tech (only in the DZ) is always in the long black cases. Food and drink is always in coolers and vending machines.
7. Always craft the advanced filter. I don't know why some players don't but it is very cheap to craft it, and it can get you to the contaminated zones. While there is some Division tech outside of these zones, there is a plethora of it in the contaminated zones, and most agents haven't been there. There are a few underground places on the map that have as many as three cases of Division tech, and extra tech can be converted to high end materials, so you want plenty of it. Also, usually contaminated zones only have a veteran or two in there and few reds. By the time you are in the DZ, as long as you are careful, veteran enemies are cake.
8.Lastly, don't be greedy towards the end of your run. If you have your caches, a couple good weapons, I prefer the G36 and Custom M44, and are feeling comfortable. Go extract. Even if you have 20 minutes left and full meds. Extract. Don't spoil a good run because you wanted more loot. Only the caches leave with you, don't get wiped by 4 elites at a landmark because you wanted one more mod for your gun. Make that hour and a half in survival worth the effort.
I hope these few extra tips combined with Treezy's guide help you get your achievement. It is a grind, but far from impossible.
