• A double-sided game board that enables a variety of starting set-ups, each with its own challenges.
• Fighter ships that give players the ability to capture and redeploy alien creatures.
• A weapon system of laser turrets that players can use to defend the space station against aliens.
• Special player powers on the tiles that can be combined in various ways.
• Four tile thicknesses to create a 3D look for the space station before it starts crumbling under fire.
• Alien creatures that can evolve to become even more powerful.
• Also due out in September 2015 is Survive: Dolphins & Squids & 5-6 Players...Oh My!, which collects three mini-expansions — Dolphins & Dive Dice, Giant Squid, and 5-6 Players — for Survive: Escape from Atlantis! in a single $20 package.
• Stronghold Games has also opened preorders for Evan Derrick's Dark Moon (which is due out June 24, 2015) and Michael Keller and Andreas Odendahl's La Granja (which bears a July 2015 U.S. release date). (I'll note in passing that after speaking with the designer and publisher, Dark Moon will stay listed together with BSG Express and not separated. I'm sure that designer Evan Derrick can expound upon this reasoning in blog posts that he plans to write about the evolution of the game to its published form.)
• Other titles due out in 2015 from Stronghold include Among the Stars: Revival, which is both a two-player only game from Vangelis Bagiartakis and Panagiotis Zinoviadis and an expansion for their Among the Stars, and a 30th anniversary edition of Code 777, with both of these titles expected to be available in August 2015.
