Metal Slug1 was my favorite arcade game. Me and my friends spend lots of quarters on that game. it was very challenging and exciting that we spend our allowance on it. We had fun playing it, and till today I remember the special moments with my childhood friends. Eventually more advanced metal slug2 hit the market and the game become so popular. Many other parts of the came after that.
I could not keep up with the arcade expensive as a kid, but luckily Metal Slug was not just on the arcade it was also on the computer. So, when the computers became more affordable my family ended up buying one, and the first game, I looked for was Metal Slug!
