It would be very interesting if the blackboxes the player leaves behind would add a little “obituary” to your PDA which could tell you how you died, what you had, and when you died. This is very intrusive but it would be very funny to also have a speech to text of what you said a few seconds before you die. (Or straight up an audio recording)
Also I would like it if we had a way of knowing what day you are on like Sub1 and SubBZ.
P.S I have actually never died so I dont know if this actually happens.
