Inspired by this summer's blockbuster "Star Trek" movie from Paramount Pictures, Star Trek: D-A-C is a fast-paced, top-down space shooter where players take the captain's chair and engage in intense online multi-player or co-op battles.

Since its maiden voyage on Xbox Live Arcade earlier this year, Star Trek: D-A-C has been expanded with two additional ship classes, a single player game mode, several new pick-ups, a new map for Assault Mode, enhanced gameplay features and more.

Star Trek: D-A-C supports online multiplayer, online co-op and single player gameplay. There are four different game types - Survival, Team Deathmatch, Conquest and Assault. In the all-new single-player Survival Mode, Starfleet captains have only three lives to blast through waves of enemy ships. When destroyed, enemy ships and drones drop special ability and score pick-ups, and players are challenged to grab as many as they can before their lives run out.  Top scores will move players to the top of the leader boards and Starfleet ranks. In Team Deathmatch, teams go head-to-head, clashing in a winner-takes-all fight to the finish. In Conquest, teams must simultaneously protect and conquer control points in space. In Assault, teams take turns trying to dominate or defend a sector of space.

In Star Trek: D-A-C, players choose from five ship types for both the Romulans and the Federation - the all-new Missile Cruiser, all-new Support Frigate, Bomber, Fighter and Flagship - with each ship offering unique capabilities for players to master and manipulate from the Captain's chair. The Missile Cruiser is a heavy artillery ship that features a longer range than any other ship in the game, but is vulnerable to close range attacks due to a low rate of fire and slower flight speed. The Support Frigate allows players to heal friendly ships and easily target escape pods. The nimble Bomber speeds in and out of battles, dropping bombs in its wake. The Fighter attacks ships head-on, blasting missiles and dodging attacks. The durable Flagship allows players to target enemies with a reticule and inflict damage with an auto-firing phaser that attacks nearby enemies. The Starfleet Flagship is the U.S.S. Enterprise™ featured in the "Star Trek" film.

New gameplay updates in Star Trek: D-A-C include variable AI difficulty settings, customizable goals that allow players to set game time limits and number of kills needed to win, improved mechanics for capturing control points in Conquest games, and host migration, which will allow games to continue even if the host player disconnects. Star Trek: D-A-C also incorporates music and signature sounds taken directly from the "Star Trek" film.

For players that previously purchased the game on Xbox LIVE Arcade, the new content for Star Trek: D-A-C is available as a free download. New players can purchase the updated game on Xbox LIVE Arcade for 800 Microsoft points.
