We’re really excited about this expansion and can’t wait to share some more details with you over the next few weeks. What we can share right now is that the expansion will feature two all-new game modes – Protector and Commando, new ships, and all new planets featuring some of our most detailed artwork to date.
We’ll also be releasing a major content patch for all players alongside the expansion pack. This patch, code named “Challengers” will update the game with new challenges and feats stretching across all existing game modes and will let you earn challenge points to increase your rank as a RESOGUN pilot.
