Unless I'm badly mistaken, TGT didn't say we'd lose the 100 points for venting the station's air, he said we'd lose the 100 points for restoring Attica station if we took the gold from the vault and ran rather than finishing off the mutants.  Just restoring the air to the small part of the station that still has some... (poisonous as it is) is a TINY cost compared to replacing the huge amount of air lost from the rest of Attica station.  And again, it's poisonous anyway... so it's not a huge loss.<br/><br/>TGT just said we'd need an attack team to keep the mutants from escaping if we vented the air.  Killing mutants that are suffocating, forced to funnel through a narrow, crowded corridor, and running into your guns is pretty simple in comparison to taking them while they're forted up with excellent cover, a great killing field, and only one small corridor for them to keep covered....
