Beating the game on Hard Mode. It really is hard! All of your damage is cut in half! Not to mention I am using different strategies than when I initially played this game.
Before I would use pretty much every Beam Weapon Missile attack, but now I'm reserving myself to just Super Missiles and the Ice Spreader. The Wave Buster and Flamethrower just waste too many missiles, and aren't worth it.
And where I used to just gun the crap out of an enemy, I now use an Ice Beam followed by a missile for a quick and missile-saving kill.
The game is getting insanely hard as I entered Phazon Mines, with those Wave Beam and Power Beam pirates...they do a LOT of damage and never die. Not to mention there are practically no Save Stations in that hell-spawned place.
Still haven't died yet. But came pretty damn close when I was going for the Power Bomb in Phazon Mines.
Just got the X-Ray Visor. Next up is collecting power ups and getting the Plasma Beam.
