The Brawlhalla Handbook.

Read the ideas. Understand the decision. Put it into practice.

I’m Dejan Carlisle-Miller / Coach Cosmic. I built this handbook from years of coaching Brawlhalla and asking the same question: how do we help a player turn what they know into decisions they can use in a match? Routes, opponent understanding, practice, and discipline all have a place in that answer.

MAKE THE KNOWLEDGE YOURS

Read. Practice. Build your next move.

Work through weapon foundations, test one decision and keep the practice that changes your game.

First step · start your Brawlhalla practice
One Handbook. Two ways to use it.

Read for understanding. Practice with a purpose.

Read the Handbook at your own pace, or work through its ideas with the Handbook Experience. The guided breakdowns bring my coaching approach to the page: what to notice, why the decision matters, what the opponent can do, and when to reset.

Public samples are open to everyone. Your free site account opens the complete book and guided experience, including private notes and progress. The experience is self-guided; live coaching is booked separately.

Inside the handbook

The Five Pillars.

These are the Five Pillars behind the handbook. Each one gives the player something to understand, practice, and bring back into the match.

  1. Optimal Flowchart & Route Creation

    Know what your route is trying to accomplish, when it applies, and when to change the plan.

  2. Frame Data Collection & Positional Mapping

    Understand what a move does and where you need to be for that information to matter.

  3. Psychological Understanding

    Watch what the opponent actually does. Build a read, test it, and adjust when they change.

  4. Execution Routines

    Practice until the action can show up when another player is trying to stop it.

  5. Proper Discipline

    Build habits that keep you learning through the good sessions and the difficult ones.

Who it is for

Players. Coaches. Esports programs.

I want players using this, coaches challenging it, and esports programs building from it. Take the ideas into practice and see what holds up.

This is part of the larger COS:CORE work I’m building. Read it. Use it. Critique it. Teach from it. If it helps you develop a better player, it did its job.

Where can I read the handbook?

Open the full 153 page source in the on site PDF window with a free account. The Handbook Experience adds weapon studies and private practice notes. The published edition is also attached to the handbook release post on LinkedIn.

Does it promise a particular rank?

The work is about development. You still have to practice, compete, review, and make adjustments. A rank comes from what you can consistently do against other players.

From the supplied Handbook · Public sample

Execution is a decision you can repeat.

Execution is the bridge between a correct decision and a repeatable outcome. Execution training should progressively remove uncertainty. The first stage isolates the input so the player can perform it without match noise. The second stage adds confirmation so the player acts only when the starter actually produces the expected state. The third stage introduces variable position, damage, dodge, height, or platform state. The fourth stage adds resistance. The final stage tests whether the behavior survives live pressure. Each stage exists because a route that works only in training mode is knowledge, not yet competitive skill.
