These extras include: a Galaga-like Challenge Mode, the aforementioned Mission Mode, Relax Mode (where you can fire to your heart's content without worrying about your character exploding), and a decent multiplayer mode. Only one card is required to partake in multiplayer, which is a definite plus. All told, Big Bang Mini is overflowing with quality content; at $20, it is a total steal.
The killer presentation and addictive challenge of Big Bang Mini is worth a purchase, and it offers what I think is the best deal in gaming since Valve's The Orange Box. No DS owner should miss this one".
