Rucksack
Rucksack is used to expand the size of the Player's Inventory in Obenseuer.
Overview
When a Rucksack is placed inside the Player's backpack slot, a button to open the the Rucksack's inventory will appear to the right of the slot. Pressing it opens the Rucksack's Inventory and pressing once more closed the Rucksack's Inventory. The Rucksack has 40 slots of available Inventory space.
In the current version there is only 1 available Rucksack however it doesn't share the Backpack's universal inventory so if an Item is put into a Backpack it will not appear in the Rucksack. There is only 1 Rucksack in the current version of the game so loosing it means loosing it forever. Police see stolen items above a certain value when they are placed inside a Rucksack's Inventory.
Any excess item's taken from a container shall instantly be put into the space in the Rucksack's Inventory.
Finding a Rucksack
The only Rucksack in the current version is in the Mines past the Radiation zone and in the small tunnel when searching for Hanss, under the first set of stairs you see to the left inside and you will find the Rucksack. The Rucksack is worth 2500
however it is the only one so it should be kept.
