Hello. Long time Bungie fan, and used to be pretty active here back in the Halo days. Unfortunately, I don't think my bnet account from back then even exists anymore, since there doesn't seem to be an option to sign in with a username and password. Anyway, I got accepted to the test this weekend, but I am unable to launch the game from Steam. When I click "Play" on steam, steam attempts to launch it, and the green "Play" button turns into a blue "Stop" button. This lasts for only a few seconds before Steam seems to kill the process, and the button reverts back to the green "Play" button. I never see the game pop up at all on the desktop GUI, although it does appear that processes are being launched before being terminated. There is no error from the game or from Steam. But I ran Steam through a terminal to get some output and help get an idea of what is happening. Here is the output from an attempted launch (Will put it in a reply since it doesn't fit). If there's anything else I can provide to help with your development, please let me know.
