Alien Syndrome (NES)

The NES Alien Syndrome is a port of a game originally by-*record scratch* SEGA!?!?

Also, it's only licensed in Japan. Go figure.

Level Select#

At the title screen, hold Down on Controller 1 and Right on Controller 2 at the same time, then press Start.

Unused Graphics#

Graphics for "H" and "A" items that never appear anywhere.

80px|Oh, get a habitation chamber

An unused frame of animation from the ending, showing the two heroes in a kiss as in the arcade version. The final game simply has them looking off into the background for the whole sequence.

Hidden Text#

The game looks for the text string OKABE at RAM address $100 to determine whether the game was soft or hard reset. It refers to programmer Naoki Okabe.
