I never realized how powerful the Drill Dash was, it's my new favorite attack :D
Also, here's a tip: Research Houdini Splicers ASAP, and use the resulting Camouflage tonic. When you put down your Little Sister to gather ADAM, stand still quickly so you become invisible, and when she starts gathering, no Splicers will come. :D
Also also, I love how when you summon a security bot with Security Command 2 it names it, I'm walking around with Jimmy right now, lol
