A new add-on for Halo Wars has been announced that promises to bring with it a host of new maps, as well as the usual addition of Achievement Points (for which gamers seem to have a never-ending appetite).

The content, entitled Historic Battles, will cost you 800 MS Points and will release on Tuesday next week (July 21st).

For the full list of new content releasing with the Historic Battles add-on for Halo Wars next week, head on down below:

• Barrens (1v1 Map): Difficult terrain channels units into killing zones. The side that controls the Forerunner artifacts will have the advantage.
• Blood River (1v1 Map): Secure base locations on nearby cliffs overlook this naturally red-tinged river. The soldiers that fought over its two narrow crossings gave the river its name, which has since taken on a greater meaning.
• Glacial Ravine (3v3 Map): A snow-topped mountain range forms a natural barrier that cuts this region in half. Control of the two energy walls at the narrow central pass often determines the outcome of the battle, though clever use of the Sentinel Factories may play a role as well.
• Memorial Basin (2v2 Map): The high ground in the middle offers good cover for infantry, while the generally open terrain transforms organized battle plans into bloodbaths.

Four new Achievements worth a total of 100 points:

• Tour Coming Through: Hot drop 50 squads to your Covenant Leader in a single game on Memorial Basin (30 points)
• Never Leave a Man Behind: Finish a game with 5000 net resources contributed to your teammates on Memorial Basin (15 points)
• Drain Cleaner: Kill 20 enemy squads with a continuous Covenant Leader Power on Memorial Basin (30 points)
• Killjoy: Disrupt 5 active Leader Powers in a single game on Blood River (25 points)
