Pretty interesting information here in an old research thread about ASW capabilities; if you hadn't seen it:

My perspective, as one who "plays" SH for entertainment and relaxation value is that I would prefer to avoid the instant death ending. A little suspense, uncertainty and drama are all enjoyable enough- but for me, it much better to be stalked, harassed and dismantled over time than to be gone in a second with the SH version of a guillotine dropping. I hate that as much as a CTD...
Looking forward to your mod and looking for the current version now.
