☕ Cup head: Brothers in Arms (Unblocked & Free)

Cup head: Brothers in Arms is a legendary fan-made boss rush game inspired by the iconic DA Games music video of the same name. This crossover extravaganza pits Cuphead and Mugman against the "Holy Trinity" of indie horror fandoms: Five Nights at Freddy’s (FNaF), Hello Neighbour, and Bendy and the Ink Machine. The game replicates perfectly the 1930s "rubber hose" animation style of the original Studio MDHR masterpiece while introducing entirely new mechanics based on these crossover universes.

This 2026 HTML5 edition has been optimized for high-performance browser play, making it a premier unblocked choice for school or office networks. It runs smoothly on Chrome books and modern browsers, with zero installation required.

💡 The Cartoon Brawler’s Starter Guide

Survival in this crossover frenzy requires mastering the unique phases of each guest boss:

• Phase 1: The Security Puppet (FNaF): Watch the present box! The Marionette uses pizza-slice projectiles and summons animatronic minions like Freddy and Bonnie. Look for the Pink Pizza Slice—it is your key to parrying and building your Super Meter.

• Phase 2: Mr. Peterson (Hello Neighbour): The Neighbour attacks from within his house frame. He fires glue to stun you and unchained bear traps to limit your movement. Stay moving to avoid his targeting pellets.

• Phase 3: The Ink Demon (Bendy): The final showdown against Beast Bendy. Beware of falling ink drops and the flooded floor. You’ll need to climb onto floating boxes to survive the ink flood while fending off ink creatures.

🏆 Pro-Level "Fandom Frenzy" Strategies

• 📐 The "Fan" Manoeuvre: During the FNaF phase, a fan will blow into Foxy’s slashing hooks. Time your jumps to use the wind resistance to hover safely past the hook’s reach.

• 🛡️ Defensive Parrying: The intermission phase features floating skulls. Some shoot pink bullets—always parry these! Not only does it keep you safe, but having a full Super Meter for the Bendy phase is essential for dealing high damage quickly.

• 🔥 Box Management: In the Bendy flood phase, ink slimes act as hazards on the platforms. Don't commit to a box too early; wait for the slime to dissolve into the ink before jumping up to secure your footing.

• ⚡ One-Shot Perfection: Like the original game, "Brothers in Arms" rewards precision. If you can clear the entire gauntlet without taking a hit, you unlock the secret "Golden Gargoyle" (Golden Freddy) Easter egg.
