Activision has dropped a schedule onto the Call of Duty website outlining the release of new maps and missions through September, 2012. The unnamed maps and missions follow the release of “Liberation” and “Piazza” for Xbox 360 yesterday (Activision says PS3 versions are “coming soon”). Other than a calendar of months more detailed specifics were not provided, but we’re excited the new maps will keep MW3 fresh throughout the year. In case you forgot, Call of Duty ELITE Premium subscribers get the new content first. See the schedule below.
