I’ve been waiting to get my hands on this game for ages as I always loved Metal Slug games and now I finally have it, although it has been out a while. If you have never experienced metal slug before then you need to. From the retro side scrolling shooting to the lovely digital and hand drawn 2D imagery this collection is perfect, it features all Metal Slugs to date, 1, 2, 3, X, 4, 5 and exclusively 6. It also includes unlockables such as wallpapers music and more, I have completed all of the games but I still go back to play them all, they never get boring. I got mine for £7.99 on PSP at gamestation and it was worth every penny. Its also on PS2 and Wii.
