A few weeks ago, when I purchased Metal Slug Anthology, and started playing each game, I have to say that this is the rarest and best compilation on PS2! I fell in love with Fio when I started playing Metal Slug X. She was the highest ranked soldier out of all of the metal slug soldiers. Those dudes from the Ikari Warriors series were really awesome when they appeared in Metal Slug 6. My favorite weapon was the shotgun. It was a strong weapon that can take out 4 enemies at once in certain situations! Fio Rules All!
