The console version of the epic Civilization games, Civilization: Revolution, just got a few new maps, and you're not even being charged for some of them.

In the Surreal Single Player Map Pack, you will be challenged to survive on maps unlike any you have seen before – some of the map names include “Mountains of Madness,” “Paisley,” and “Patterns.” This map pack will be available worldwide on both Xbox Live and the PlayStation Network and will be free.

The Survival Single Player Scenario Pack tests your bravery across map-based scenarios: Ice Age, Global Warming, and The Eye. This scenario pack will be offered worldwide on Xbox Live for 100 MS Points, and on the Network for $1.25 US.

I haven't been keeping up with the game, so I was surprised to see that 2K had already released other content, including more free maps and for-pay scenarios.

The Victory Scenario Pack includes three new scenarios for gamers to tackle in single player mode. They include "Enlightenment" where players show off their civilization's grandeur as they vie for a cultural victory, "Hyper Drive," a high-speed space race, and "Gold Rush" where amassing money fast will win the game.

CivRev included some cool gameplay variations/scenarios right out of the box, but I'm glad to see developer Firaxis is keeping them coming. These sound like lite variations on some of the cool gameplay challenges fans have made for Civilization IV for the PC.
