Yes, Nack was aware he was about to be double-crossed. Okay, so this was a little more mundane way of dealing with the situation, but theres something to be said about the classics.
Indeed. The ol' Double Double-Cross. Hmmm, Yeah that's what it's called...
He's always scheming isn't he
Ok how many double crosses has he done now?
wow, i didn't think he'd actually get infected by the X
He looks kinda cool in that position.
I wouldn't worry, X infestation seems to take a few hours at least. Samus managed to finnish her mission and get back into orbit before her infestation made her lose conciousness in Fusion's cinematic.
