The first Halo: The Master Chief Collection Insider test of the year is now active, bringing forth the recently promised flight for Insiders to test before the content is pushed out to everyone. This latest Insider session, version 1.2159.0.0, is now live for Xbox console players as well as PC players across Steam and Microsoft Store. Insiders will find Halo 3 and Reach being the testbeds in this flight and 343 Industries is looking for feedback on the new content, the biggest of which is easily the two fresh maps hitting Halo 3. Titled Waterfall and Edge, these head over from the now-defunct Halo Online project.
