The upcoming Free2Play MMO WildStar has lifted the restrictions from the closed beta. It is now an open beta.
At WildStar, they plan to switch to a Free2Play model with WildStar: Reloaded on September 29 at 6:00 AM our time. The exact time for the switch was recently announced.
To test all of this, a closed beta has been running for a while. It has now been converted into an open beta. There were apparently issues with expired keys, and Carbine decided “Unleash the beta!”, from which everyone now benefits.
You can find the client to play on the test server here: http://wildstar.patcher.ncsoft.com/PTR/WildStarPTR.exe (This will start a download).
