Jumping from Metal Slug 3, MS4 is quite dissapointing as it's quite a step-down when it comes to the spectacle and chaos from it's previous 2 entries, i'd say it returns more to the feel of MS1 but i found the levels a bit duller and just more of the same stuff which is fine, the game is still a through and through metal slug game and i found the music to be quite pleasing.
