Now this is a fun game. I tell you what. This is a fun game. I got mine off ebay (sorry amazon but the prices...) anywho the game is really cool. i think theres like 39 metroids you have to kill but the deal is yoru go though the disturbed planet fothe metroid sr388 and have to kill them all. and after you kill a certain amount theres this rumble and the lava in a big shaft room goes down to the next floor and this goes on for like 4 times. When you then get close to the "lordess" metroid -so fine- you have to fight i think 9 new metroids! which is a add on the prevoious 39 so technically theres 48 (49 if you include the queen) anyways then you anilate the lordess and for some reason on my game theres this weird red line on the wall but whatever it goes donw after teh battle and for some ohter reason theres a little excape hole under the lordess. so i guess you can wimp out and excape kinda ruins the point of a boss if you can jsut "escape"?! but oh well after you defeat IT. then a baby metroid hatches (jimminy crickets where do all these things come from!!!! fun never ends with metroid 2 ;) but then you escape the terrifing planet and go to your ship. THE END review DARN GOOD GAME
