Yep, just got past there though this morning (took me four tries total). I just retrieved the grapple hook and have no idea where to go from here. I only have two energy tanks, probably why the Alpha Blogg was so difficult. I hear the game really picks up about halfway through (Sanctuary, I presume).
StarCraft 1? Probably my favorite game of all time. I'm not very good at melee either, so don't feel bad; I've always been a UMS player. This computer is ancient, but I've got my StarCraft Battlechest kit with me, maybe we can play sometime (provided my Brood War disk still works)? You play on US East, I presume?
1. After Grapple... well, do you have the Boost Ball already?
If you already have the Boost Ball, your next upgrade is the Seeker Missile System in the Temple Grounds. If you already have the Seekers, look for the Torvus Temple Keys.
You can get at least four E-Tanks (you get one from in Grounds when you destroy your first Missile Door, one sometime before fighting Dark Samus 1, one in Agon Wastes in a Morph Ball tunnel near the Temple, and one in the Hydrodynamo Tunnels, which requires the use of the turbine jets and well timed Bombs). Those are off the top of my head, 2 and 3 may be the same one.
2. I have to figure out how to fix the discoloration on SC1 before I can play it on my Win7 laptop (the other computer... well, network access is bust.) There was a patch driver or something somewhere on the internet, but I don't remember the link. I would be on US West.
