: Yeah... There are very, very few invincibility powerups in all 3 games put
: together, and none of them are on vacuum levels or near large bodies of
: liquid. (Incidentally, it's also possible to drown under lava if you
: somehow live long enough; it drains oxygen as well as health.)
I was thinking about that and wondering if there were any legitimate cases where one could encounter this bug in the original Marathon series. I know I came upon it legitimately, but I think it was with a 3rd party scenario. In M2, off hand, if one manages to deplete most of their oxygen under water in prior levels and then goes for the secret under-lava terminal in Where the Twist Flops, this should be possible. That sure would come in handy for grabbing that underwater ammon in Beware of Abandoned Rental Trucks. I'm not sure if there are similar examples in any of the net maps - I would bet that there are, but players may not live long enough to find out.
