Yeah, I killed the first one with a mere revolver. I did die 4 times before I caught on that the charge doesn't follow your movement, but is instead a straight line. AFter that it was easy sailing.
Also, the recoil decrease upgrade to the Suomi-konepistooli(ehehe) is awesome. Or rather, the weapon worthless without it, which brings me to my actual point.:Guns are completely useless on their own. I understand that the game is supposed to encourage using both forms of offense(plasmids and weapons) in combination since most of the former have some kind of debilitating effect like freeze or stun, but later splicers eat lead like mad. I feel like playing Unreal sometimes, in a bad way. That game was absolutely notorious for having castrated all weapons. That said, telekinesis(die droids, die!) and other crazily effective plasmids like upgraded electro shock do remedy that.
All things said, SS 2 wasn't a lot better, until you got the hang of different ammo types.
