The event is available starting today, and will run until the 1st of January, 2022.
One of the big draws is the free 10-pulls where every week pilots will be able to do a free 10-pull as part of the GBO Winter Festival 2021. According to Bandai Namco Entertainment, you’ll be guaranteed one 3-star or higher mobile suit from the pulls.
The event will also feature additional free 10-pulls during the last two days of the year, giving fans a total of 30 pulls that week.
The festival will also introduce a new mobile suit, dubbed the Varguill from Moon Gundam. Similar to the Sazabi, this mobile suit uses funnels to dispatch its enemies in space, and will be available via a special banner running until September 16th.
On top of that, the game will also feature a new event mission, where fans can unlock the Jegan D-type, running alongside the Winter Festival.
Finally, Gundam Battle Operation 2 will also be welcoming back old pilots as well as new ones with a special returnee event. You’ll gain increased DP and CP by logging in during the event.
