Arms updated to version 1.1.0, adds spectator ‘Arena’ mode and LAN mode

Update: Full patch notes

• ”LAN Play” support added. You can now battle against players via LAN. On the Top Menu, click and hold the Left Stick and then press L+R to switch between “Local” and “LAN Play.”
• ”Arena Mode” added. This mode focuses on serious 1-on-1 matches and can be played via “Friends,””Local,” or “LAN Play.” Up to 4 players can be in the arena, and players not currently fighting watch as spectators.
• Fixed issue where Kid Cobra was able to repeatedly do a charge dash while riding snake boards.
• Fixed issue where Barq would warp a great distance away after Byte & Barq perform a rush attack while on a snake board.
• Fixed issue where ARMs such as the Chakram would pass through the purple light boxes in the Ribbon Ring stage.
• Fixed issue where Biff referred to the “ARMS Grand Prix” as the “AMRS Grand Prix.”

The first software update to Arms is here and it does more than just add stability.

Spectator mode is now an option for friend battles. You’ll be able to pick ‘arena’ when starting a match, it’ll put four players into a lobby and friends fight 1-v-1 while the other two watch and then the rest watch.

The update also adds LAN play. You can Switch between LAN mode and wireless by pressing down the left stick on the top menu and hitting L and R. There’s also fixes for Kid Cobra, Byte & Barq, the purple boxes on Ribbon Ring, and a typo.
