Konami announced Metal Gear: Social Ops, an upcoming smartphone game, at this morning's Metal Gear 25th Anniversary event. GREE chief operating officer Yoshikazu Tanaka unveiled the game's first trailer, showcasing its 3D graphics in the Unity engine, before announcing a worldwide release later this year.

According to Andriasang, Social Ops revisits stories from previous MGS games, features a card-based battle system, and has Mother Base development options reminiscent of Peace Walker. Attendees at September's Tokyo Game Show should find out, as a playable build is scheduled to be there. In the meantime, Famitsu has a couple of screenshots to check out.
