Hoarding

OP-2 is a game about hoarding, among other things. This page attempts to explain the mechanics related to collecting items in the game.

## Is hoarding really required?

As explained in more depth on this page, it isn't. All these chain/hoarding quests are optional and only required for a single questline and achievements. Some chains also feature good rewards and can be done with relative ease, though.

## Standard containers

Standard containers you see throughout the game are limited to 50 items in their capacity. This is done because the X-Ray engine can't keep up with the massive amount of items players tend to keep in one location.

There's an item called Lock, obtainable from Akim. In older versions of OP-2, it was needed to reduce the probability of NPCs stealing from standard containers. Since OP-2.1, they don't steal from standard containers anymore, so the locks are useless. 10 locks are still required for Doctor's chain quest, though.

## Rucksacks

Throughout the game, you will obtain Rucksacks. They can be dropped onto the ground to create custom stashes. Rucksacks are highly optimized for hoarding and you can easily keep thousands of items inside them. By default, they feature a list-based interface; if desired, they can be switched into the classic icon-based mode. Each backpack contain a GPS tracker and can be seen on the PDA map, with all its contents displayed in a tooltip.

The best way to store your Rucksacks is in out-of-bounds areas that people will never come to, such as the Bar's vast out-of-bounds area on the right side.

## Theft

NPCs occasionally steal items from your backpacks when you aren't around, even on different locations. There's no point in hiding them because NPCs don't have a concept of obstacles or height when looting. They exist on a 2D grid, and have a certain chance to steal a backpack if they happen to come within 25m of it. Keep your stashes away from typical stalker routes to not have them stolen.

The best way to keep your stashes is out of level boundaries. There's no navigation mesh there, and your possessions are safe from NPCs. Many levels have easy OOB exits in OP-2, especially Bar, so this can be easy. However, on some locations OOB exits are complicated enough to make that impractical.

If the backpack is stolen, the GPS tracker still keeps tracking the thief movements on the PDA map, so you won't lose any items. You'll have an option to buy the contents back from him for 50 000 RU, or to kill the thief and grab the lead note from his body. The lead note is encrypted; any trader could decrypt it for 60 000 RU. In either case, your stash will return to its place automagically, there's no need to haul everything back.

NPCs don't steal from vanilla containers, with the exception of a couple bugged ones (the box near the campfire at abandoned farmstead in Army Warehouses being one example).

## Guarded stashes

Dropping a backpack in the vicinity of a trader will create a guarded stash. You'll have to pay money daily, but the trader will keep an eye on it, and it won't be stolen.

## Carrying weight

During the game, you will increase your maximum carrying weight by various means - armors, artifacts, and consumables like "Hercules". One notable way to increase your carrying weight is Grav-suit, which is a reward for Unique suits, a quest given by Skinflint. It could be further upgraded later in the game.

## Bulk transport

There are working vehicles in OP-2. You can use them to transport large amount of items, as you can drive with any amount of items in your inventory, regardless of being overloaded.

Vehicles have infinite fuel, but drive terribly and are vulnerable to damage. The "bread loaf" UAZ found in ATP seems to be invulnerable.
