Realism with mass and volume

The real inventory limit is 60 liters. Now 400 liters, does the player hold the whole room?

The real weight limit is 80 or 100 kg (without exoskeleton). With exoskeleton 200 - 400 kg. Now it is 1 ton. At the same time, a massive exoskeleton in a spacesuit is not visible, where does such power come from?

- Why doesn't the player slow down under heavy load (weight)?

The idea that follows from this:

- Add 2 new items to the game: Backpack MK1 (gives volume 45 liters), backpack MK2 (gives volume 60 liters), backpack MK3 (gives volume 75 liters for inventory). Changes the appearance of the Engineer.

Exoskeleton MK1 (increases the tolerated weight limit to 200 kg). Exoskeleton MK2 (increases the weight limit to 350 kg). Exoskeleton MK3 (increases the tolerated weight limit to 500 kg). * - The exoskeleton consumes the energy of the spacesuit while moving, and the more heavily loaded the player, the more energy it consumes per unit of time.

* - You can check the box for the exoskeleton (extreme mode). What is he doing? Increases the capabilities of the exoskeleton by 25%, however, in this mode, the structure of the exoskeleton is gradually wasted.

* - Add to cargo containers (warehouse) a threshold of the retained mass of resources. If the threshold is exceeded, then the structure of the warehouse will gradually decrease.
