As someone big into roguelikes this definitely reads more “inspired by roguelikes” instead of a roguelike mode. You are essentially wagering gear on each mission with the gear all having associated monetary costs/difficulty in acquiring through vendors. The closest comparison in an existing modern game would be Dead by Daylight.
That’s still a good thing, though. I just think it’s silly that failure conditions are so standardised in gaming with any possibility aside from save reloading (either to a checkpoint or depending on game wherever you like) generally going unused- So “like a roguelike” is the only way IOI have to describe it.
Kind of like how nearly every game with melee combat is described as “like Dark Souls” at some point, and up until a few years ago every open world game was “GTA/Skyrim with ____”
