Blueprints are now available in Cities XL, which means players can build Megastructures that are inspired by real buildings like the Eiffel Tower and the Statue of Liberty. More information on blueprints can be found in this FAQ or this article on the game's official Web site.

Since many players may want to check out how blueprints work before subscribing to the Planet Offer, Monte Cristo is giving every player who registered an account a free weekend to try them out on Oct. 31 and Nov. 1. Current Planet Offer subscribers will have the two extra days of game time added to their accounts.
