More details were revealed about Daemon x Machina during the September 2018 Nintendo Direct. We learned about possible equipment options, character upgrades, and saw a clip of multiplayer.
You hop into your Arsenal to find a runaway AI. You can gather weapons from beaten enemies and bring them back to your base. These can be equipped to your character.
In addition, you can leave your Arsenal. This allows you to explore the world. Your avatar in Daemon x Machina can be customized. When your human form gets new skills from these updates, your Arsenal will change and gain new skills as well.
4 players online co-op will be available in Daemon x Machina. This will allow you to fight giant bosses with other people and perhaps team up to have a better chance of taking them down.
Daemon x Machina will launch on the Nintendo Switch in 2019.
