User blog comment:Codgod13/Evil round 1: SHODAN vs GLaDOS/@comment-4277633-20110812181850

Let's see... in Portal 2 we saw computers of GLaDOS' type could be outfitted with bomb proof shields and a bomb thrower. Add this to GLaDOS' control of the Aperture Science facility (with many Rocket Sentries and Turrets offering rocket launchers and machine guns to the fight) and her neurotoxin, plus she has control of ATLAS and P-Body (two androids) among other unknown stuff.

I think the vaults of Aperture Science will serve GLaDOS well!
