There was no way to turn off your exoskeletons. You had to unequip the battery to stop it from draining all the power. Now you can just press a button to turn the exoskeleton your wearing off and on, but that's not all...
Features
The basic exoskeletons give only a small carrying capacity buff but don't worry. You can upgrade the exoskeletons multiple times, upgrading the carrying capacity. And at high levels, even adding a shock absorbtion system to reduce fall damage, but be careful! Upgrading your exoskeleton with new parts adds weight, resulting in a bigger penalty when the exoskeleton is off.
So grab your exoskeleton, equip a backpack and head out. Looting and carrying logs won't be a pain in the ass anymore unless you run out of power...
I tested this mod in MP and SP and it seems to work fine.
You don't need the original STALKER Functional Exoskeletons mod, but the STALKER Armor Pack is required!
