Microsoft has announced the first DLC for Halo Wars. Entitled “Strategic Options,” the pack will contain three new game modes for players to compete in or with players via Xbox Live as well as 100 new achievement points to gain in these new modes. The modes are Keepaway mode, Tug of War mode, and Reinforcement mode.

• Keepaway Mode is the “Halo Wars” adaptation of Capture the Flag. Teams will battle it out to capture a free-roaming Forerunner Sentinel to score points before the other team. Capture three sentinels to claim victory.
• Tug of War Mode is all about having a stronger army than the opponent. Defeating enemies is essential, but success is determined by a combination of the army, buildings and resources left standing in the end.
• In Reinforcement Mode, all active battle units are provided in successive waves. Players must adapt their tactics and use the ever-changing set of units to outwit and outlast the enemy.

Hit the jump for the new achievement details. The release date and pricing (guessing 800 MSP) will be available soon, so check back for more news!

The new achievements are:

• “One and Done” (30 points): Score the winning point in a game of Keepaway against Legendary A.I.’s
• “Pull Hard, Pull Deep” (20 points): Win and never trail in a Tug of War game
• “Freak on a Streak” (20 points): Gain at least 15 population from a single wave in a Reinforcement game
• “Living Loving Bug” (30 points): Obtain a Scarab during a Reinforcement game
