Storage
You start with an empty backpack that may contain 100 kg and a portable battery that may hold 100 energy.

These can be upgraded when finishing a 100-missions game and also a bit by supporting the game under "Account" and "Support this game".

Automation
You have access to an Automated mode (you need to enable it) that lets you pick up and drop energy and material at facilities automatically when in range.

This way you can play without even having the app open and may focus on other things during the walk.

Progress
It is a single player game but you can compare you progress to how other players have performed in the same amount of player time under "Statistics". There you have access to some graphs and information.
