SC just released thier PTU and is now allowing every backer into it. https://robertsspaceindustries.com/comm-link/transmission/14442-Public-Test-Universe-Launched "Get ready to join the Public Test Universe (PTU.) During the lead up to Arena Commander 1.0, we gave a limited number of backers access to what we call the PTU, a version of the game that offers experimental versions of upcoming patches. Starting today, all Star Citizen backers have access to the PTU and with it access to test a build of Arena Commander 1.0.1. Please note that the PTU is not for the faint of heart: unlike standard Arena Commander, you’re one of the first people testing a new build which can often be unstable or otherwise non-functional. If you’re serious about helping us test Star Citizen, accessing the PTU and reporting bugs on the forums is one of the biggest services you can provide… but if you’re looking for a clean dogfight, you may want to stick to the standard build. You can report bugs discovered in the PTU here, or provide feedback on the PTU itself here. Arena Commander 1.0.1 is now available on the Public Test Universe. 1.0.1 is a bug fix-oriented patch, designed to fix a number of issue we saw with 1.0. The next major content patch will be 1.1, which will introduce several long-awaited features to the game. Official patch notes will be available once the release is tested on the PTU and pushed to the main release channel, although in-progress notes will be posted to the PTU forum."
