Konami is also known for its password, the Konami Code, which traditionally gives many power-ups in its games. Although variants also exist, as in the Parodius series, and button naming can differ depending on the controller used, the classic NES combination is: ↑, ↑, ↓, ↓, ←, →, ←, →, B, A. However, use of this code in more recent Konami productions has been sparse.
