As others have said, this game is HARD. It's not frustratingly hard though. It's a lot of fun, and it doesn't get old. It has a great challenge mode, which allows you to unlock various things upon completion. The best part about this game is you can unlock the original Contra (NES) and Super Contra (NES) by completing challenges. To me, the game is worth purchasing just for that!Get more detail about Contra 4.
