Frank-ProvoSNK Playmore has revealed that the company is putting together a compilation pack of Metal Slug games for Sony's PSP handheld.
The compilation, tentatively titled Metal Slug Collection, will include all six games in the series–Metal Slug, Metal Slug 2, Metal Slug X (a remake of 2), Metal Slug 3, Metal Slug 4, and Metal Slug 5.
No word yet on PSP-specific enhancements, although the company did confirm that ad hoc 2-player co-op would be supported.
Look for Metal Slug Collection to ship toward the end of the year.
