Upcoming game Titanfall is now opened up to beta testing for all Xbox One and PC users, according to an announcement from game developer Respawn Entertainment.

"We have limited server capacity for the beta, but would be good to hit that ceiling," Respawn founder Vince Zampella tweeted this weekend.

A later Tweet said, "Ok, just heard from [Respawn programmer Jon Shiring]. His words are 'Let's break it', so the plan is to make the beta fully open and have you max stress it! All the switches need to be flipped, and there are probably lots! It will take some number of time units to do it all!"

Both versions of the game were launched by Sunday evening.

"Over the next couple hours we'll be getting all the PC people who signed up access through the My Games Library in Origin," Respawn tweeted Sunday. "If you don't see it in your library yet, hang tight! It'll be appearing over the next couple hours for some users as it rolls out."

"Data servers are slammed! Apologies for those trying to get in, doing our best to improve wait times (& more servers will be up at launch)," a later Tweet said.

The game is available in the New Game Demos area of the Xbox Game Store reported Polygon. Previously gamers had to be issued access codes to join the beta. The beta will be available until Wednesday at 6 p.m. PST.
