Originally slated to operate until mid-August, the Xbox 360-exclusive beta formally kicked off on June 25 and was made available to those Xbox 360 owners who purchased Backbone's Wolf of the Battlefield: Commando 3.

The extension is likely aimed at testing a new patch for the fighter revamp, which Capcom says will arrive "in the coming weeks." The patch incorporates a new netcode which minimizes lag while playing the game online, as well as a number of general gameplay tweaks.

A complete listing of the patch notes are viewable below.

From Capcom's blog:

• Crash while joining games has been fixed.
• Headsets no longer transmit constantly. (Please note: on some Arcade Sticks, the connection to your headset can be a little wonky, so if you're hearing static, check your connections!)
• Ken�s strong Shoryuken no longer juggles.
• Ken�s fierce Shoryuken now only juggles for a maximum of 3 hits.
• Ken�s roundhouse Hurricane Kick now leaves him slightly farther away from the opponent on hit.
• Default round number has changed to 5 for Ranked and Tournament matches.
• Win/Loss data now shows up in Player Matches.
• Game Speed has been fixed to match the original arcade game.
• Game no longer crashes when trying to select Akuma by the old code.
• Super Finishes now display correctly in 4:3 mode.
• Game no longer crashes when signing out during a Tournament.
• New netcode to reduce lag generate by packet loss.
• New rewind code that mitigates latency by smoothing out what people see on screen.
