Private beta tests for Halo: Combat Evolved on PC are expected to roll out next month, a little later than initially planned.
In a post on the official Halo forums (thanks, Windows Central), 343 Industries recently invited players to participate in an upcoming "flight" limited content - the developer's own vernacular for a beta test - of Halo: Combat Evolved ahead of its formal release later this year.
"We are looking to flight and gather feedback on a wider range of content prior to its launch this year," the post said. "These areas are focused into the following gameplay elements which will include validating dedicated servers, peer-to-peer connections, crossplay between Steam and Windows version, new UI for customization in [Halo: Combat Evolved], and the next season's progression for H:CE."
