Sony and SNK Playmore have announced today that Metal Slug 3 is coming to PS4, PS3 and PS Vita.
Adam Laatz, director at SNK, promises that the emblematic 2D run & gun action shooting game will feature "some of the highest-level quality of NEOGEO emulation seen on PSN yet" when it releases on the PlayStation Store. The game will also release with a few online features, but no details regarding this online component were revealed.
Metal Slug 3 is scheduled to release sometime this Winter. It has yet to be confirmed if the game will have Cross-Buy support.
