From Insomniacs Newsletter:
On when we could expect the beta to begin:
Just in case youve been blissfully living underground, we want to remind you that there is a war with the Chimera going on. Would you kindly help us fight them off? All you have to do is fill out this form for the chance to apply to join in on the Resistance 3 Beta, which is starting soon. Those of you randomly chosen to brave the Bullseye bullets and Auger assaults will be treated to a sizable slice of the revitalized Resistance 3 multiplayer weeks before its full release.
If you arent among the first recruits given access to the Beta - dont fret. We will be randomly distributing codes to a select few throughout the duration of the Public Beta. All are welcome to apply, but only some will be chosen for the opportunity to truly resist. Are you one of them?
On when we could expect the beta to begin:
http://www.insomniacgames.com/update-on-resistance-3-beta/Wanted to give you a heads up about the Resistance 3 beta, when its launching and how you can get access. Starting next week, you may begin to see some of your favorite Insomniacs and others on PSN playing the Resistance 3 Beta. We are launching our Friends and Family beta next week in order to test our servers out before the mad rush of public beta users from SOCOM 4 and EU PlayStation Plus. We will be updating our servers, configs and patching the beta during the course of it to be sure were ready for the public beta in August, as well as the release of Resistance 3 on September 6th. We expect to run this Friends and Family beta over the next few weeks.
This is important, as many of you are holding early access vouchers to the public beta from SOCOM 4. The public beta is tentatively scheduled to begin in early August for those who got Early Access vouchers from specially-marked copies of SOCOM 4 in North America and for PlayStation Plus subscribers in SCEE territories.
