Those familiar with the Fate series may recognize the characters in the above trailer. Fate/Grand Order is a continuation of the series and a reboot of Fate/Apocrapha.
Featuring an original story written by Kinoko Nasu and Yuichiro Higashide, this RPG-style game has you assemble a team of characters from the Fate series, summoning them as "servants" via gatcha, and leveling them up as you go through the game's story.
It just so happens that now is an excellent time to join in on the fun, as the GUDAGUDA Honnouji is currently in progress and will be ending the day after Thanksgiving. During the event, a mini story centering around Oda Nobunaga will be available, and you'll be able to obtain exclusive servants.
