Thunder Force IV/Ruin

This is also a rather easy level. Simply use the weapons you got in the last level to blast your way to the mini-boss, but be wary of the long gray ships that come from above and below – they shoot solid electricity beams that temporarily trap you in between them, limiting mobility. One thing to be careful of is the multiplying metal things. They will continue to multiply across the screen in a line, and you can only kill them by killing the first one in the line. If you find a Snake weapon, save it for the boss. When you get to the mini-boss, hit him with your Twin Shot or Blade, dodging his fist and flying between his bullet spreads. When both arms are gone, enemies will start to fly in from the background, and he will shoot large lasers from his legs, so be careful and keep blasting.

After he is dead or runs away, the rest of the level is the same as the first part. Be on the lookout for a Hunter weapon, and unless you trust in your evasion skills, save it for the next level. Pretty soon the level boss, Hell Arm, will charge onto the screen and begin firing energy balls from its claws in your general direction, as well as regular shots from its body and an occasional missile spread. Switch to the Snake you've been saving and get above or below him, using it on his claws. Once the claws are destroyed, the arms will begin to shoot streams similar to the GargoyleDiver's foam blasts. At this point use your Blade or Twin Shot to hit his head. Keep plugging away until he dies.
