Starmade Alpha is a creative sandbox shooter inspired by the Indie hit Minecraft that revolves around building amazing ships, stations and other structures, blowing them up and just straight up having fun with others in its likeminded community.
Ever dreamt of building the USS Enterprise and flying it around fighting AI-controlled enemies and other players? Ever wanted to fight in space battles and see your ship slowly taking damage block by block from incoming fire? Or are you the kind of person that likes to spend hours upon hours to get that reactor set up just right for maximum efficiency and output, ensuring your victory through technological supremacy and ingenuity of design?
You can do it all!
In Starmade you can build almost anything you can imagine, watch it get blown apart or watch it blow others apart, form alliances and fight over territory and faction homes, organize races and pretty much do anything you can think of. And if the game lacks certain things you would love to see, drop your suggestion on the forum and motivate it, Starmade gets updated on an extremely regular basis and everything in it is open to suggestion and critique.
Already the game is packed with features like salvaging, stealth modules, intricate power systems, fully simulated ship-physics and much more!
You can find out more via the wiki page http://wiki.starmade.rtag.me/
