NIS America has released another batch of media for its upcoming strategy RPG, Natural Doctrine. The screenshots and trailer, viewable below, focus on the game's multiplayer options, which sees players build up a force using cards and decks to use in co-op missions or battles against other players.

In addition to offering cross-save across all three of its platforms — PlayStation 3, PlayStation 4, and PlayStation Vita — the game also allows multiplayer cross-play. Natural Doctrine is due out on September 23 in North America and September 26 in Europe.
