From the announcement:
Fantasy Flight Games is proud to announce a new edition of Mission: Red Planet, the steampunk-themed board game of planetary exploration designed by Bruno Faidutti and Bruno Cathala.
In Mission: Red Planet, two to six players compete to control as much of Mars and its priceless natural resources as they possibly can. This edition maintains the core mechanics of this fast-paced game while incorporating updates by the original designers. Astronauts can land in a new zone, the moon Phobos, and the Soldier can convey astronauts from Phobos to anywhere on Mars. Missions and Discoveries have been fine-tuned, and new Action Cards join the Event deck. The game can now handle six players, with rules for a two-player variant also included. What's more, the Victorian steampunk aesthetic has been refreshed with all-new graphic design for a more contemporary look.
