: I found this really odd behaviour in the first vacuum level of the Gemeni
: scenario, and wonder if it's a bug in AO or Marathon or a feature of some
: kind: I was running out of air when I found an invulnerability powerup.
: The powerup lasted longer than the air. But instead of croaking when the
: air ran out, I got this loud absorbtion burp and then I suddenly didn't
: need air any more. I could keep on playing with zero air in a vacuum level
: - even after the invulnerability wore off.
: Has anybody else experienced this?
Engine thing, I first noticed it in that first vacuum level from the original M1 - when you run out of air, it's a local damage thing. If you've got invincibility, the damage is negated - and once you're at 0 air, and alive, you can't get negative oxygen, so, unless you refill, you're pretty much immune to running out.
Someone else said it better in '97, I think.
