Gears of War: Ultimate Edition developer The Coalition has announced that a Gearsmas event will commence later this week.

Celebrating the upcoming holiday season, The Coalition has revealed that it will be holding a seventeen-day-long event for Gears of War: Ultimate Edition, running from Friday, December 18 at 12 p.m. PDT until January 5, 2016, at 12 p.m. PDT.

Double XP will be in full effect for the community event, as well as the addition of two new multiplayer modes for Gears of War: ‘BTTE TDM’ and ‘Shotty Snipes.’

BTTE TDM is two vs. two matches on small-scale maps for “intense co-operative skirmishes,” while Shotty Snipes has teams competing against one another with only the Gnasher Shotgun and the Longshot Sniper Rifle at their disposal.

Gears of War community manager TC Octus posted on the Gears of War forums that “due to the much longer running time of this event, the Warzone playlist will remain active throughout the Gearsmas period.”

As well as the update rolling out this Friday, The Coalition has been adjusting the map rotation system, resulting in the “most popular maps for Ultimate Edition appearing more often.”

Last month, The Coalition implemented a playlist update for the title, which included the removal of three multiplayer maps — Bullet Marsh, Rooftops and Garden — due to multiple issues that would occur in matches.

However, it seems that the developer is now ready to reintroduce the maps to all of the Ultimate Edition’s multiplayer modes excluding Execution, with TC Octus suggesting that the maps “now appear less often than other more popular choices.”

“Thanks for all your incredible support over this year — we can’t wait for you to see what’s in store for 2016 when we lift the curtain on Gears of War 4,” TC Octus wrote.

Gears of War 4, which The Coalition unveiled at Microsoft’s 2015 E3 press conference, will have an upcoming beta scheduled to take place in early 2016, which will be accessible to those who purchased the Ultimate Edition.

Gears of War: Ultimate Edition, which was also announced at E3, was released on August 25, 2015, for Xbox One, with The Coalition and Microsoft also confirming that the title will eventually be making its way to PC.
