Latest update for Halo: The Master Chief Collection has arrived

“In Halo 3: ODST, we’ve done more than just add the Flood to Firefight!” writes Alex Wakeford on Halo Waypoint. “Players can now use the VISR map to see enemy locations, even while waiting to respawn, in Firefight matchmaking. Players can now use the Energy Sword and Sentinel Beam in ODST for the first time ever, and can even spawn with these weapons in Fiesta Fight. We’ve also mixed new enemies (such as Elites and Flood) into the wave lineup for various Arcade variants in Firefight matchmaking.”
