: I'll have to try this... Looking at player.cpp line 207 in the Aleph source,
: we see that the only damage type allowed to bypass invincibility is fusion
: while the suffocation code (line 1103) attempts to perform suffocation
: damage. Are you talking about the original game engine or Aleph One?
I believe I first encountered it with the Infinity engine, but I "remembered" it again while fooling around with Marathin Fell, which has a lot of vacuum levels, using AO and the Infinity Game Wimp to, well, cheat. After my earlier post, I wanted to refresh my experience, but quickly. Sure enough, no O2, no death. I just went back and tried it with Infinity, agian using the game wimp to add invincibility to a saved game. Same thing - I ran out of O2 and lived. Not only that, but I could indeed change levels and dive under water and surface, all without oxygen. My guess is that suffocation damage is a one-time event that occurs only when you run out of oxygen, but not when you are already out. If you're invincible at the time of suffocation, you will not die and you can then live indefinitely without oxygen. This is clearly a bug, and a rather glaring one at that.
