CupHead: Brothers in Arms

CupHead: Brothers in Arms is a challenging 2D battle inspired by Cuphead, where you face three bosses back-to-back in a single run — Marionette, Neighbor, and Bendy — dodging bullet hell, parrying pink projectiles, and keeping your finger on the trigger the whole time.

CupHead: Brothers in Arms is based on the fan-made song "Brothers in Arms" by DAGames and the animated short of the same name by Oblivionfall: Cuphead finds himself in yet another impossible situation and must fight his way through three powerful bosses, one after another.

Instead of classic levels, you're thrown straight into a series of boss fights: Marionette, Neighbor, and Bendy each take the stage in turn, and your goal is to survive the entire gauntlet with only a handful of lives.

Just like in the original Cuphead, every enemy attacks in multiple phases, and everything revolves around pattern recognition, precise jump timing, dashing, and parrying.

Controls and Core Mechanics

The controls here are a step up from your average runner — you'll need to juggle several buttons at once.

• Movement — arrow keys (left/right).

• Jump and air parry — Z.

• Shoot — X.

• Lock aim mode — C, to fire without moving.

• EX Move (powered-up attack) — V, once you've built up enough special cards.

• Dash — Shift, to slip through danger.

• Pause — Esc.

Players in the comments note that this keyboard layout feels pretty demanding: jumping, parrying, and hitting dash at the right moment all at once is genuinely tough, and some users are asking for a more familiar setup like arrow keys + spacebar + Z, or gamepad support.

Boss Fights: Three Trials in a Row

The game is built around three major battles, each one feeling like its own test of reflexes and endurance.

1. Marionette (Puppet) — a brutal warm-up. First up is Marionette (Puppet) — a puppet boss with a visual and conceptual connection to Five Nights at Freddy's-style animatronics.

It fires off volleys of projectiles, summons smaller enemies, and the arena fills up fast — you barely get a moment to breathe: jump, dash, shoot, jump again.

Players in reviews often say this boss has way too much health, and they "only make it to the first flag" before the later phases even begin.

The key here is constant shooting (X) and careful jumping (Z), while pink projectiles can be parried to build up cards and fuel your EX Move.

2. Neighbor — sharp attacks and precise aim. Next comes Neighbor — a direct nod to the creepy antagonist from Hello Neighbor.

At this stage, attacks get more aggressive and come from multiple directions: you'll need to lean heavily on Dash (Shift) and Lock mode (C) to shoot the boss without exposing yourself from a safe position.

In the comments, players admit they "die instantly" here because they can't react fast enough to the wave of projectiles and support enemies.

The better you know the attack patterns, the smoother the fight goes: the developer emphasizes that the attacks mirror the Brothers in Arms animation and aren't random.

3. Bendy — the climax and the ultimate endurance test. The final boss is Bendy, the iconic Ink Demon from Bendy and the Ink Machine.

By the time you reach him, you're already worn out from the two previous fights — and Bendy piles on even more projectiles, faster attacks, and trickier trajectories.

Here, parrying pink objects and using your EX Move become practically mandatory: without powered-up attacks, it's nearly impossible to deal enough damage before you run out of lives.

One wrong move — a mistimed jump, a late dash — and the screen gets absolutely flooded with enemy fire, sending you back to the start, because this fan-made version has no checkpoints between phases.

Bullet Hell and Difficulty

CupHead: Brothers in Arms feels like pure, concentrated Cuphead cranked up to max difficulty: three bosses in a row, a limited number of lives, and a relentless barrage of attacks.

On YouTube and in the comments, players say the game is "just as hard as the original" — and some even find it harsher, thanks to the density of projectiles and the lack of any levels in between.

Players are asking for:

• reduced boss health,

• shorter phases or added checkpoints,

• remappable controls or gamepad support.

That said, many praise the game for its atmosphere and the fact that the combat genuinely feels like "real Cuphead": tight patterns that demand memorization, and a powerful sense of satisfaction when you finally pull through.

For younger kids and newcomers, this can be an incredibly tough challenge — but teens and adults who love hardcore games appreciate it for exactly that level of difficulty.

Short Sessions, Intense as Hell

A single run lasts just a few minutes.

But in those few minutes, you'll be completely drained: three bosses, constant focus, zero margin for error — or it's back to square one.

At its core, this is a "one more try" kind of game: jump in fast, push a little further than last time, learn a couple of new patterns, and go again.

Can you beat CupHead: Brothers in Arms in one run?

Theoretically yes: you need to defeat Marionette, Neighbor, and Bendy back to back with a limited number of lives and no checkpoints; the creator and some players confirm that a full run is possible, but it requires practice and memorizing patterns.

How much harder is CupHead: Brothers in Arms compared to regular Cuphead?

Players and video reviews say the fan game is at least as hard as the original: three bosses in a row, no checkpoints, and dense bullet hell make it very intense, especially for those used to the breather levels in the main game.

How many bosses are in CupHead: Brothers in Arms and who are they?

There are three bosses: Marionette (Puppet), inspired by animatronics from horror games, Neighbor, a reference to Hello Neighbor, and Bendy from Bendy and the Ink Machine, all of whom must be defeated in a single sequence.

What techniques do you need to master to get far in CupHead: Brothers in Arms?

According to player feedback, the most important things are learning to parry pink projectiles, making active use of the Dash, shooting in Lock mode to minimize exposure, and memorizing the attack order of each boss, since the patterns are not random and follow the Brothers in Arms animation.

Who made CupHead: Brothers in Arms and is it an official game?

This fan game was created by a developer under the nickname omega glitch, it is based on the song Brothers in Arms by DAGames and an animation by Oblivionfall, and it is not an official part of the Cuphead series, the rights to which belong to Studio MDHR.
