Ahh, gameplay. 2D shooters live and die by their gameplay, and thankfuly
Metal Slug X has more than enough of that. The game is short, and you won't be unlocking any super secret modes or anything as you play, but the adventure is fun enough to return to again and again.
Metal Slug X is an expression of a genre that just about died in the early nineties, and as such it will appeal to the old-school gamer almost instantly. But even more recent initiates into the fold of gaming should find a lot to like here; the action is fast, the humour is apparent, and the game's a lot of fun.
I won't even pretend that there's a plot here. The main concept of the game is the same as pretty much every 2D shooter ever made--Go Right and Shoot. This basic principle can be applied in full force throughout this game, as you scroll from the starting Left Side to the inevitable boss encounter on the Right, blazing away at enemies the whole way through.
The situations you're put in are usually rather unique, ranging from the Middle East to where the aliens roam, and they look nice enough to distract you from blowing up all of the bad guys. And there are tons of bad guys. They pour in from both sides, but usually from the Right, and it's up to you to destroy them. You have unlimited ammo with your starting weapon, but there are the inevitable powerups that give you better weapons--machine guns, homing, et cetera--but have limited ammo. You also have bombs, which do serious damage but are limited in both range and count.
And then there are the Slugs. You can pilot a number of vehicles, ranging from the everpresent tank (Metal Slug, which the game's named after) to the aforementioned camel. They all have serious firepower in the form of cannons, and they can also take multiple hits. You, of course, can only take one.
What more is there to be said? The game's short, yes, but shooters usually are. The real pleasure in the game comes from playing through it over and over, perfecting your style and getting the loss of lives down to a minimum. If that's not your idea of fun, you should definitely avoid Metal Slug X, but you probably aren't reading this review anyways.
