1-on-100 is one of five Multi-Player gaming modes found in Arms, where friends either online or locally will battle against each other. 1-on-100 pits one single player against an staggering wave of enemies, one hundred of which to be exact, that must be defeated in succession and as accurately as possible. Since it will be extremely difficult to defeat all one hundred opponents with just one single character, the main goal is to see how many you can take out before being defeated yourself.
