Surviving Mars just got a permanent price drop to $29.99 to go along with the the free Sagan update that includes a new difficulty level and hardcore challenges. Players will now face 24 major challenges with their own parameters for success including sponsor, game profile, active game rules and map coordinates. Challenges will now be more difficult with time constraints, adding an extra layer of difficulty for the player and the dome dwellers to overcome. Basic skill with the game will allow players to complete the challenges with a good rating, but only the truly strategic will be able to best these new challenges with an excellent rating. More information on surviving mars and the new challenges in the Sagan update can be found at their website.
