Call of Duty: Black Ops 4's private Blackout beta has been available on PS4 for several days now, and in that time the mode has received some notable tweaks and adjustments. Developer Treyarch detailed another list of changes it has made on Reddit, further refining the beta's stability and introducing its second special event, Close Quarters.

Close Quarters has replaced Wednesday's special playlist, the faster-paced Fast Collapse. As its name suggests, this new event is all about close-range combat, featuring only SMGs, shotguns, handguns, and old-fashioned fisticuffs. On top of that, Treyarch has added four more Black Ops characters to the playable roster: Mason, Menendez, Reznov, and Woods.
