StarMade - PC & Mac (Steam)

Key Features:

• Procedurally generated infinite universe, with quadrillions of galaxies - The universe is massive. It'd take approximately 10,000 years to cross from one end to the other! Singleplayer and Multiplayer worlds can be heavily customised with our extensive config options.
  
• Developed for scalability- We have a broad range of graphical and performance options that cater to our low-end users as well as those with heavy rigs and servers.
  
• Advanced Build Tools - Powerful and easy to use building tools, quickly design awesome ships, stations and bases. Including functions: Copy & paste, undo, redo, replace, symmetry modes, shape assistance systems (spheres, cycles, torus and more) and rotation of templates.
  
• Modular Weapon Systems - Combine weapon systems for countless configurations of weapons. From sniper beams to swarm missiles.
  
• Comprehensive Rail & Logic Systems - Use the rail system to build moving parts. You can do anything from simple elevators, sliding or rotating doors, to complex cranes.
  
  Tinker with our logic systems to control any system in the game, be it weapons, lights, rails, or explosives. Logic covers all basic gate types for convenient use (AND, OR, NOT, DELAY, Flip-Flop), allows in flight control and wireless connections between entities. You can use it for simple things like timers, switches, buttons. Or, build complex systems like working clocks and even a real CPU.
• Community multiplayer (dedicated servers) - Play with others in our community hosted servers. Our configs allow administrators to customise core game mechanics for a tailored experience. Most settings can be tweaked to squeeze the best performance out of hardware.
  
• Platform independent (Windows, Linux, Mac) - StarMade is completely platform independent. We support the three most widely used operating systems.
  
• Free to play in alpha - We offer the full game free to play while in alpha development. Play our game through this period for free while in return we receive invaluable feedback and bug reports.
