In case people are around for PAX on Thursday and want to try indie games, xbox will hold a free event at building 92 (that’s the visitor center in the Studios area) to play indie games and Halo 5. Some 343 people will be on hand. Free shuttles from the convention center to Microsoft Redmond from 4:30pm on.
