Twenty years ago today, the Sega Genesis was released in North America. Known as the Mega Drive in Japan, the Genesis was a big hit. The NES was dominant at the time, but that fabled console was a bit long in the tooth. With the help of truly superb marketing (Sega does what Nintendon't!), and a certain blue hedgehog, the Genesis became Sega's most successful console. It was also a great way to play co-op with a friend, with many stellar co-op games in the Genesis library.

As promised in our last column, we'll take a look at Sega's Altered Beast this week. First gaining fame as an arcade hit, Altered Beast eventually got released for the Sega's classic Genesis system. Back before Sonic (it's hard to remember back that far, isn't it?), Altered Beast was the pack-in game for the Genesis. You'd better hope you sprang for the extra controller, because Altered Beast was a co-op fan's dream.
