At a developer roundtable event on June 11 during the E3 video game conference, Nintendo announced Code Name: S.T.E.A.M. exclusively for the Nintendo 3DS family of systems. The new turn-based action strategy game comes from Intelligent Systems, the developer of the Fire Emblem and Advance Wars series.

Like the Fire Emblem and Advance Wars games before it, Code Name S.T.E.A.M. tasks players with planning out strategic moves using a team of soldiers to do battle with enemy forces.

For starters, the game takes place in a steampunk world, weaving its globe-spanning tale in the art style of a classic comic book. The title refers to an elite team of steam-powered special-forces soldiers composed of absolutely wild and wholly unexpected characters. The game uses a behind-the-shoulder perspective at the level of the players’ squad. Players outflank and outshoot the enemy in a 3D battlefield with a customizable four-member team. To defeat aliens, they have to take cover, set up ambushes and unleash crossfires and counter-attacks. For every move taken or action performed, a steam gauge is slowly depleted, forcing players to use strategy to achieve their objectives. Along the way, players will acquire new items and weapons that give them more strategic options and firepower.

Code Name: S.T.E.A.M. will launch exclusively for the Nintendo 3DS family of systems in 2015.
