It's the way she usually greets Space Pirates.
Kill first, greet later: Samus' motto in a nutshell.
maybe they should have tried throwing a rock with a message tied to it at her...
She'd throw it back, on fire, with a plasma grenade attached XD
Reminds me of Wild Wild West.
"Shoot first, shoot second, shoot last, and then when everybody's dead, try to question someone"
...or something like that.
Methinks she's so used to killing Space Pirates its become second nature, despite the situation...
Thats our samus! :P
