What the hell? Meta Ridley is the devil himself! I tried about 6 times to kill the bastard with no luck(and each fight taking about an agonizing hour of pain and evil). I'm not offended, just amazed you found him so easy.
The really annoying thing was both our healths went down at about the same rate, one time, his health was so low one hit would kill him, but so was mine. I had just charged the plasma beam but he lept at me, I tried to jump but he killed me. I still hear Samus' screams at night.
