Brutal.io Physics & Mass Calculator
Calculate your flail's exact hitbox radius, momentum drag, and maximum throw range to perfectly time your combat strikes.
The Illusion of Damage
Unlike traditional shooters or RPGs, Brutal.io does not possess a health or damage system. Combat is binary: if an opponent's flail touches your car, you instantly die. Because raw damage doesn't exist, mastering the game requires understanding Mass and Momentum Physics. Collecting energy does not make you hit harder; it makes your flail larger, granting you a massive defensive and offensive radius.
Momentum Drag & Turn Radius
As you use the calculator above to increase your energy, notice the Momentum Drag (Lag) metric. A spawn-level car (10 Energy) has a tiny flail that follows mouse movements almost instantly. However, an Apex-level car (25,000 Energy) drags a massive weight. When a heavy car makes a sharp turn, the flail continues moving in its original direction for a fraction of a second due to inertia. Skilled players use this "Swing Lag" to whip their flails around corners and crush pursuing enemies.
The Art of the Throw (Detachment)
Clicking your mouse detaches your flail, hurling it forward. The Throw Distance is directly tied to the momentum you built up before releasing. While the flail is detached, your car is incredibly fast but completely defenseless. A common top-tier tactic involves throwing a massive flail through a cluster of small players, then using a "Black Hole" gravitational pull to yo-yo the flail back to your car, harvesting their dropped energy.
Frequently Analyzed Queries (FAQ)
Can a small flail kill a giant car?
Yes. The car chassis is completely vulnerable. If a 10-energy spawn car manages to maneuver around a 25,000-energy giant's flail and tap the giant's car chassis, the giant will instantly explode, dropping massive amounts of energy.
Why do I lose energy when I die?
When you are eliminated, you drop roughly 60% of your total stored energy as free-floating geometric blocks. The remaining 40% is taxed by the arena. This prevents the server from experiencing infinite energy inflation during long matches.
What do the Green Sentinels do?
Green Sentinels are environmental hazards that act as energy leeches. If your detached flail touches them, they will rapidly drain your collected energy until you reattach the cable. Avoid throwing your flail near them unless strategically necessary.
