Just beat the first level. The boss looks like a giant version of the standard ships you shoot down in the original. Go for the week spot at the top.

This will unlock once you complete the first stage. To kill the boss just keep shooting until you get to the weak spots, which are yellow. Hit that spot a few times and he will die.
