Metroid 2 Return of Samus was released by Nintendo in November 1991. This is the second game in the series of Samus battling the evil aliens to save the world and vanquishing more Space Priates one at a time. This game in the series builds up suspense leading into Super Metroid for the SNES.

60 Missiles and Full Health
Go to your Metroid ship and then you have to roll left to right, you have to hit both walls. Once you do it correctly you will get 60 missiles and 99 health.

Invincibility
Start the game and roll 10 times back and forth stand up. Do a flip in the air after that and you will have invincibility.

Boss Tactics
You might want to hang on to the 7 energy tanks you find for the end boss, the queen. You have to shoot her when her mouth is open, roll inside her gaping jaw and when she retracts her head back, roll towards her stomach and lay down 3 bombs. In total, it takes 15 bombs to kill her, and doing this takes a lot of energy if your a newbie. The tanks will come in handy.
