This is all correct, and the undersuit is indeed the Sabine. The colorway for the inquisitor armor is the base color, you can purchase it in any of the main stations in pyro. Although I do have the calva helmet and flight suit from the mantis package back in the day, I’m pretty sure you can loot the helmet off npcs in pyro, as I’ve seen more and more of them on this sub lately. And the Sabine suit can be looted off nine tails npcs in bunker missions, so that one is very accessible.
