All fighters will be unlocked during the week-long beta, but progress will be wiped when it's over.
Capcom is bringing a number of new features and enhancements to the "Capcom Fighters Network online experience" for Street Fighter V, including improvements to matchmaking, faster loading times, more updates to the rage quit penalty system, and better friend management options. To show them off, it's also offering a free week of online play, running from 1 pm ET on March 28 until 12 pm PT on April 3, with all fighters unlocked including the newcomer Kolin.
The free week is actually an open beta intended to test the CFN updates, and also the balance changes made for the upcoming Street Fighter V season two. "We understand that Street Fighter V’s server performance has been a less than optimal experience for many of our players. The improved CFN experience is the result of rebuilding it from the ground up to address the most pressing issues that will ultimately result in a better online experience," Capcom wrote on Steam. "That said, we want to collect feedback and ensure everything is optimized for launch. We will be giving PC players a sneak peek of what’s to come while putting the new CFN through its paces with an official PC Beta Test."
