For the uninformed, the Nintendo Switch comes with 32 GB of built-in storage that can be easily depleted by digital content such as the aforementioned Arms Global Testpunch. So, if you are running out of space, then we recommend taking a look at a compatible Micro SD card such as the MicroSD EVO Select Memory Card from Samsung (which you can check out with this link on Amazon).
The aforementioned Arms Global Testpunch, which is available now for download, have two trial periods. The first will take place from May 26th through May 28th while the second one is from June 2nd to June 4th. All ten characters will be playable and there will also be offline local multiplayer to go along with the online exhibition matches.
Arms will be released exclusively for the Nintendo Switch on the 16th of June in the North American region. If you are interested, the fighting game is available for preorder with this page.
