Your death means leaving all of your equipped weaponry where you died, and being sent back to the beginning of the tower. Getting to your body means teleporting back to the fatal floor and fighting back through it with whatever subpar weapons you had in storage. Plan on dying again on these corpse runs, as you run into the enemies that killed you earlier - this time while you have B-list weapons. Once you finally have your A-game weapons back, you have to find an equipment station. In the far future it's really hard to equip items, apparently, because you can't do it on the fly. So, plan on dying even more - while you desperately try to get ready for battle once again.

Another infuriating oddity is that every weapon has limited uses, even items such as swords. Once your sword has run out of ammo - yes, a loaded sword - you can't just swap it for a working sword without running to an equipment station or getting a lucky power up.
