Bolt Thrower is currently single player Space Shoot 'Em Up. It’s still work in progress and updates will happen whenever I can find the spare time. Every effort is being made to detach game data from the code, being 'data driven' anyone can change the look or functionality of the game. So I've exposed the data through a XML configuration file rather than lock the data into the code.
Version 0.70 is now released - see Changelog You can download latest version from the link provided or just run an older version of the game and it will ask if you wish to update. The update feature is available in versions from 6.0 and above.
