Nintendo started off their E3 Presentation with a fast-paced, mecha action shooter game called Daemon x Machina. This mecha game comes from Marvelous Entertainment, produced by famed Armored Core producer Kenichiro Tsukuda, with mecha designs from Macross creator Shoji Kawamori, and character designs from Yusuke Kozaki (Fire Emblem series, No More Heroes series).
From the Nintendo Treehouse livestream, Tsukuda-san explained the concept of the game, as well as its mechanics while showing a gameplay demo. DxM is set in a post-apocalyptic world where AI has evolved and turned hostile against humans (much like Terminator, anyone?). Also, there appears to be fragments of the moon that have crashed on Earth for some reason, and these fragments actually power the arsenals the players will pilot.
Character customization is present, with a handful of facial and body options to choose from. The hangar also shows extra spaces for docked arsenals from multiplayer partymates aside from yours. Story progression is pretty much mission-based, and will take the player all over the world, dealing with various terrain, AI adversaries and big bosses.
On the field, one of the unique features of DxM is the ability of your arsenal to pick up armaments or mecha parts, and install these on your own mecha on the fly. These scavenged parts can be imported back into the hangar once the mission ends. Graffiti are also hidden on the map for you to search for. Finding these graffiti will unlock additional paint options for your arsenal.
The E3 2018 playable demo is limited, but more details will come up in the future.
Daemon x Machina will be out for the Nintendo Switch on 2019. Watch the Treehouse live down below. Skip to the 6:29-hour mark for the DxM demo.
