GT reviews Contra 4 (DS), which has both the original Contra and its sequel Super C as unlockable games. Video after the break. Click here for first picture in gallery. Here’s the bottom line:

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
