Ooooh, understand! Thank you. In game it looks like i can take two or three different items instead of one. Now it's clear, thanks! Very nice game btw :)
I think it's may be a silly question and i'm a dumb, but i have no idea how to use backpack to increase active-items space. I equip a ruck sack or backpack as passive item and what's next? I still got just one space to put active-items in there. Help please :)
