I already know that it saves the current inventory (from its description), and although you can save and quit anywhere, it will still load at the area of the last save checkpoint.
But are there other information that is saved? Like the status of:
- items/loot lying around, dropped or otherwise (and their location)
- opened or unopened item boxes
- bodies lying around (if a limb is cut or if the body is blown to pieces, is this information also saved?)
- scavenger bots status (including location and time left before they return to a bench)
- status of rooms unlocked with Torque Bars
- which missions are currently selected and active
- suit upgrades
- ammo left in clip
