This mod adds a reinforced gas mask, a new type of power armor: an Armored Personnel Unit and two weapons that can be used effectively with it.
Armored Personnel Unit: A body frame which offers more advanced protection than marine armor, functions as a jump pack with three charges, and 70% vacuum resistance. Slower movement speed when wearing it.
Armored Helmet Module: Offers slightly more protection than a marine helmet, offers 30% vacuum resistance and the same accuracy buff as a gunlink.
Powered Cleaver: Does slightly more damage than a monosword at a cost of much slower hit speed.
Autocannon: A rifled version of the vanilla minigun, offers more bullets per burst at 8 damage with a slower reload speed.
Reinforced Gas Mask: Adds a gas mask with the same protection values as a vanilla simple helmet.
This mod is not meant to be completely balanced with vanilla as it was developed for my own personal playthrough tastes. All items except the reinforced gas mask are ultra tech.
