Go to the Xero Series website to play a beta. The beta will be releasing Monday along with a trailer. The BETA will most likely be featured here on Newgrounds on Tuesday.

EDIT: In the betas (only), there will be an FRP status text box. It will be there to show the Frames per second. The game is set to 30 frps but that status box will not be featured in the full game, however, by pausing the game you may activate "FRP Indicator".

Also, watch out, screenshots are just right around the corner.
