Contra 4 is great Contra Fan Service. The core game design is a fresh fight that stays true to the 8 and 16-bit editions. At the same time, you can unlock two of the games that the fans hold near and dear, and via an in-game museum you can view the series' timeline through boxart and screen grabs. You should be aware that the Contra 4 game design will be one of the toughest challenges you'll ever face on the Nintendo DS. Even though it doesn't do anything tremendously new, it's a game that'll really separate the men from the boys…and it'll give casual gamers an appreciation for design that's been lost to the ages.
Overall score: 8/10
