Due to some closed beta tester keys expiring, Carbine has decided to remove the need for a key altogether and has opened the doors wide for anyone who'd like to download and try out WildStar's F2P version before it hits live service next Tuesday.
Hey Everyone – We’re aware that there are some people experiencing issues with their beta keys expiring. Upon further investigation we’ve decided to remove the need for them altogether. Come on in and give free-to-play a taste test by downloading the test server client (http://wildstar.patc...WildStarPTR.exe), logging in, and having fun. See you on Nexus! Team WildStar
