Power Armor can be adapted to any alien race with a little bit of thought.
Vargr in battledress.....err....nice doggy?
I remember a supplement for the Starship Troopers rpg which added oceanic powered armour, and EVA powered armour.
A wishlist:
Existing:
'Standard' Battledress (got)
'Heavy' Battledress (got -
Mercenary Artillery Battledress)
'Superheavy' Battledress - aka mechs (Ah, Mr Brazer...)
Special Environment:
Oceanic Battledress
EVA Battledress (wouldn't take much modification)
Hot-zone Battledress (either radiation or temperature)
Military specialty:
'Light' Battledress - recon gear, less protection, more about the endurance boost.
'Logistics' Battledress - aka SARCOS/HULK (today) or the Aliens powerlifter - again, less protection, this time more about the strength boost and with integral cutting/lifting gear so an infantry section in this stuff can do the job of a contemporary recovery vehicle.
Civilian/Emergency Services: (Same technology but nothing really battle about it)
'Hot-zone maintenance' Battledress - a suit for doing something like emergency reactor leak maintenance (sort of like the Judge Dredd Holocaust Squad's suits)
'Construction' Battledress - wouldn't have thought this was economically viable except for very unique circumstances where conventional construction vehicles can't reach the site - mining/tunnelling/explosives demolition work seems the most likely suggestions.
'SWAT' Battledress - Not sure what the differences would be in requirements for a police hostage rescue/assault team compared to marines, but integrated drones, sensors, stunsticks and smoke/stun grenade launchers are in, and FMGPs are most definitely out! Range becomes less of an issue, as does maintainability, but fine control is more of one. Allowed to be more 'brittle' - stopping slug and gauss fire is a must but plasma weapons or emplaced guns are not something you need to concern yourself over, so you're allowed to fold like tinfoil under really big guns.
Plus a range of 'best of the rest' - common makes of battle dress in use by other powers, especially for non Humaniti species. Ape battledress, and (definitely!) uplifted dolphin battledress. I would love to see some dry-environment battledress for an uplifted dolphin. Look out, players, Flipper's gone Robocop on you.
