Just wondering how I find out if there's a new build and what build mine is
When you turn on the game, in main menu, under the NEO Scavenger logo you have the build number and date printed.
Current build number is: 0.971
Just watch the "News" section to know when the new build is up!
If the game is bought on desura, you can right click it and then clicking View Chengelog, it will show you everything
