Awesome game its tons of fun and will have you playing for a while there are also unlock able extras its just great if you have ever played a metal slug game you know its fun so now on the go its even better with 7 games in 1 its a must play for the psp system!!
Metal Slug Anthology is an awesome game, it takes me back to my UC days. I used to play Metal Slug X on the coin-op machine. It includes the newest Metal Slug 6 which is not available anywhere except in this collection. The only flaw this game has in comparison to the console version of the game are loading times. It's painful to wait. After you complete a level the PSP loads the next and the approximate time of waiting is of 10-15 seconds and not to mention before even loading the main menu of the game selection you have to wait almost 40 seconds. I would recommend the console version because loading times are much faster. Its still a great game but considering how much processor power the coin-op machines use, the PSP emulates these games very well given the handicapped processor speed of the PSP.
