not the sky scraper sized mechs more like the vital suits form lost planets.
mini mechs? basically balanced enough that your not obliterating mountains in a single shot, but with lots of utilities to be a useful transport/ battle suit.
give them functions that allow them to carry inventory and equipped various different weapons/tools, but need resources to power (probably something like the T energy from the game series.)
say chainsaw to cut down trees drills for mining cannons and lasers for battle.
