We've released the 1.3.1 hotfix to Helium Rain to account for two new issues.

• Fix failure to start on Linux devices
• Fix mod launcher failing to start while not logged on to Steam

• 12 playable ships with weapon and engine upgrades
  Play fighters, bombers, cargos, corvettes or capital ships.
  
• Realistic economy model
  Take advantage of an accurate simulation of space trade to be the most competitive company. If diplomacy fails, blockades are in order.
  
• Fast-paced combat with a Newtonian flight model
  There is no speed limit in Helium Rain. You can fly at half a mile a second while aiming backwards !
  
• Localized damage model for spacecrafts
  Aim for critical systems in order to disable ships, kill their crew or capture targets.
  
• Procedural contracts, world exploration, technology upgrades
  Pick contracts and build your empire.
