Milestones have been upgraded and now include all sorts of fun activities to earn free credits every day!

Platinum keystones now exist, enabling you to trade 1:1 for free credits! Unlike most systems, every single credit milestone possibility is open each day, enabling whatever your favorite playstyle is to fuel your credit desires. With a focus on group activities, we encourage everyone to work together to gather as much as they can (up to 20 a day). But, if you like, solo does just fine.

Come read the specifics in our forums, and take part in helping us make it better. Already so many ideas are flowing that the original 75 options will soon be expanding.
