Still good
Not to sound whiny, but the weakest part of this was probably how this was harder than the previous version. I could certianly not find any other difference between the two games. This is still fun to play because it had all of the great gameplay the previous game had. It is sure satisfying when you get to hear those soldiers yell out in horror as they are killed. There are simply a neverending series of them coming! It seems like the powerups were harder to get this time.
My favorite weapon remains the laser because you have so much freedom to zap whoever you want. Another great touch was that the graphics were very authentic to the game. It was also cool to see that little guy go out and give you stuff. I think that was the first time I ever saw him being used in a Metal Slug game (apart from the first one). It does get annoying with how few weapons you seem to have.
