The year of Halo on PC is rolling right along. We’ve checked off several PC Halo releases already this year and by lore order Halo 3 is next up to bat. As with the others, 343 Industries are inviting registered members of the Halo Insider Program to what they call “flights,” basically a big beta test. Instead of continuing to pick select groups of players, 343 say that they’re shooting off an invite to the current Halo 3 test to all registered Insider members. The test is scheduled to end on June 26th.
