A few hours ago uberPenguin took to twitter to announce that the private beta period has ended. This will now mean all beta testers will no longer have access to the game, but instead this will be available to staff only, in preparation for the public beta release.
As an extension, uberPenguin has also left a quick note on their website in regards to this displaying a maintenance page, as follows:
Not long now! Uber is in its final stages of perfecting the server in preparation to its estimated public beta release of June 8. To clarify, uber will no longer accept further beta testers.
As Speedy CPPSHQ has exclusively revealed many of uber’s features earlier, we’re sure you’re all uber excited to finally checkout the server! Make sure to tune in to uberPenguin’s Twitter account to stay in the loop.
