Arknights: Endfield is an open-world adventure mobile game, and many players are curious about what M3 means in Arknights: Endfield. In Arknights, M3 is actually an abbreviation for Mon3tr, the summoning creature of the operator Kelxi. However, as a sequel to Arknights, Arknights: Endfield introduces various new and intriguing settings for players to explore. Below, I will make some bold speculations about what M3 could be based on the previous game.

Firstly, let's discuss the possible role and function of Mon3tr as a summoned entity. As a summon, M3 naturally needs to have high combat power and strong survivability, which can assist its master as either a damage dealer or a tank in the front line, capable of precisely bursting down enemy units. Additionally, based on the setup from the previous game, M3 might also have resource collection or terrain destruction capabilities.

Moreover, as a game that emphasizes resource regeneration, M3 could also serve as a driver of industrial technology. Here’s my speculation regarding M3’s potential role as a piece of equipment. M3 might act as an industrial manufacturing machine, aiding in raw material processing or the synthesis of advanced materials, thereby enhancing the base's internal automated production capacity. Furthermore, M3 could be an indispensable part of the base's defense system, fitting well with the construction and tower defense aspects of the game.

Lastly, talking about the potential entanglement of M3 with the storyline, given that the game continues the worldview of the predecessor, I speculate that M3 may be related to technological organizations like the Dijiang in the main story. Players would only encounter it as they progress through the plot.

Above is my reasonable speculation about M3, based on the official information and the setting of the previous game. Do the fans of Arknights out there have their own speculations about this tactical unit M3? If so, go ahead and share them with your friends.
