Level your PMC to lvl 5 with quests/pmc runs to get access to the flea market!
Use your scavs on interchange – this hasn't changed! in addition to that, with the hideout items, its even easier to make money.
Shitty paint style scav loot run map: https://i.imgur.com/N6YJTr2.jpg – my go to is the red one. Usually half the route is already enough (limited backpack space or valuable items already found – then gtfo).
Usually a loot run will last 10-15 mins and make you about 200k roubles. Depending on luck, you will make a lot of more (hideout items). Most of the time i am surviving 5-7 runs out of 10.
What to loot? With the addition of the hideout, you can loot everything.
Weapon Crates make good amount of money. Many raids they aren't looted, because they are in high risk areas (e.g. around kiba)
Hideout items can be very rewarding, but they are complicated. Loot them and remember what items bring you the most.
Dont shoot scavs (only when they have expensive gear). E.g. if you have no backpack, but this juicy scav has a scap bp, it could be worth to kill him to use the scav bp for your scav run. If you are the more risky type of guy (scavs can get pretty dangerous, especially when your are looting and have no meds with you) you could kill all the scavs and loot them.
Loot dead scav's backpack and pockets for bitcoins, keys and labs keycards and hideout items.
Put items, which you need, in your stash and save them for your weapons.
Sell everyting what you dont need!
If you want to level your traders, you should sell and buy gear from them to, to get the money requirement
If you buy items, always check the flea market first to get the cheapest offers
Buy Armor and especially helmets from the flea market. They don't have do be 100%, 75% is enough!
Don't waste to much time on boring scav interchange farm runs. Try to pick the fights if you are there and kill other players. Do it fast, do it for fun. Do it to get full geared into your next raid.
Be the capitalist at the flea market. If you sell something, put it 1 rouble below the lowest offer, not 10, 100 or something else. Exactly 1. If you want to sell items fast, undercut them by a little bit more than 1, e.g. 2-5% or 10-100 roubles. Do this only if you are selling only one item. Certain items, e.g. labs keycard, you don't have to undercut. They will be sold quite fast if you put them higher than the lowest price.
With Hideout items, you do not have to undercut! usually they are sold asap at the flea market!
Get the most out of your capitalism – level your traders, buy items which are in high demand and sell them (e.g. Ammo from Peacekeerp LVL 2-4)! Many player will hate your for that, but it makes you money!
