The APAT MK-2 is a drastic upgrade to the APAT MK-1, having an air tank paired alongside a toggle-able air filter in case of having to go for lengthy periods of time underwater, trapped underground, or maybe even in space if the time ever comes because the suit is airtight. It is also equipped with a more efficient battery that is much more space efficient, able to last for a full week of operation before running out of power. The visor is made out of an inch thick bullet proof glass, with the helmet custom made to withstand even harsher punishment than regular helmets. The suit is also made to withstand extreme heat, pressure, and radiation, with lead lining right under the ceramic and steel armour layer, with insulation and padding, alongside a small AC system within the suit to keep it room temperature.
this is inspired by the 1-51b power armour from fallout uhhh ig me
