"Fans of the Contra series will probably find a number of things to smile about in Neo Contra, and they'll also discover that, despite the game's very short length, it offers some decent unlockable extras--some additional weapons, characters, and features like a gallery with concept art. Nevertheless, since the game itself is a simple, straightforward shooter without much meat on its bones and without any terribly impressive graphics or sound to wow you, it probably won't last you long. It can be pretty fun for a while, though, so it's a fine choice for a rental."
