Unlock Cheats
There are four cheats in the game, and you'll need to beat 2000 baddies to get them all. The first allows you to increase your starting number of lives to nine. The next lets you select stages. The next level unlocks Alpha Cody and Alpha Guy as playable characters (and lets you change costume colors). After that, you unlock the right to rapidly punch. All of these cheats will be available from the Options screen.
