Starting on January 26 at 12 a.m. PST, all in-game queue and "Happy Hour" bonuses will count for 256% their usual value. The XP-grinding lasts until this Sunday, January 30 at 11:59 p.m. Plus, if you jump into a game tomorrow between 10 a.m. and 5 p.m. PST, you may find members of the Zipper staff on your team.
The developers are also introducing a "Faction Neutral" switch for Domination and Acquisition modes. The two modes will be open for any factions instead of being PMC-specific for the first time. Like the XP boost, this lasts until January 30 at 11:59 p.m.
