This game is fun, a lot of fun. good sound, good gameplay, horrid shortness. you can beat the whole game in less than a hour if you have played the other metal slug games. I cannot write a full review on the game at the moment so i just made it short just like the game.
This game would be good never mind GREAT if it were a free internet flash game. But the reality is that its not and as DS game it doesn't make the curve. Contra 4 has a massive amount of content including the original COntra and Super C but Metal Slug 7 has a measly 7 missions. Sure there are 70+ missions in the combat school but I didn't rent this for minigames I rented it for old school shot em up action. The graphics again resemble a flash game still using faded Neo-Geo sprites. Going back to Contra 4 Metal slug should have done something like this with the graphics just making it clearer and less pixelated. One good thing is that it doesn't use the touch screen gimmick and sticks to classic controls. All in all if your a fan this is worth your time to rent not buy but id just skip it and go with Contra 4.
