The interview begins with an inquiry into how the project started. Tsukuda says that when thinking of how interesting the Nintendo Switch's portable and table modes were, and of a project that would be able to make use of these, he got an idea for a mecha game.
When asked about what sort of game it is, Tsukuda says that the player assumes the role of a mercenary known as an Outer, who uses a powered suit type mecha called an Arsenal to fight enemy AIs. The player can take weapons from defeated enemies and equip them immediately, and can go freely between the ground and air. Due to this, choosing the right equipment loadout for where you fight is important.
Tsukuda says that the title is derived from Greek "deus ex machina". As the player advances in the game and becomes an ace pilot, they become "something like a god or demon" to the enemy, and that is what resulted in him changing "deus" to "daemon". He purposely went with "daemon" instead of "demon" due to its use in computing, but cannot go into details due to its role in the story.
Tsukuda says that when they first began development, many of the staff were not used to the comic-style graphics, and things like shadows ended up still looking realistic. It was only after he told the person in charge not to be afraid of doing things differently and to make something to match the style that the solid black shadows were made.
The interview concludes with Tsukuda saying that Daemon X Machina tries out many new things, and Kawamori saying that it will be a game worth playing, and both hope that people will look forward to it.
