We just finished up our coverage of Metal Slug 6 for the PS2 when SNK Playmore informed us that the game will join the Metal Slug Anthology! Metal Slug Anthology is now a seven game collection with Metal Slug 1-6 and Metal Slug X. The game comes out for PSP and the Nintendo Wii this November. SNK has said that they are working on Wiimote features exclusively for the Wii version. One idea they mentioned was using a lobbing motion to throw grenades.
