- Quick Answer: The piece argues that Devil May Cry’s signature combat didn’t come from a planned design vision, but from an accidental bug that made enemies launch into the air.
I have always found accidental game mechanics fascinating, but few mistakes have had a legacy quite like the one behind Devil May Cry.
The series’ iconic combat can be traced back to a bug in another Capcom game.
While Onimusha was in development, a bug would send enemies flying into the air after a hit.
Hideki Kamiya was intrigued by the strange behavior and asked programmer Kazunori Inoue whether they could recreate it for his own project.
That project was still being developed as an early version of Resident Evil 4.
It already featured a targeting system built around firearms, so launching an enemy and then holding it in the air with repeated gunshots offered an unexpectedly natural combination.
The prototype eventually strayed so far from Resident Evil that Shinji Mikami encouraged Kamiya to turn it into a separate game.
That game became Devil May Cry, and the chain of events that led to it still feels almost too simple to be true.
An enemy was launched into the air by mistake, Kamiya liked the result, and one of the most influential combat systems of the last 25 years grew from there.
Why Did Launching An Enemy Feel So Revolutionary?
I think launching enemies changed the rhythm of combat because a successful hit could now open up more possibilities instead of ending the exchange.
The idea of a strong attack throwing an enemy backward was already well established.
A powerful blow might send an enemy across the room or knock them down, but the interaction usually ended there.
The Onimusha bug suggested that sending an enemy airborne could open up entirely new ways to continue attacking.
That transformed vertical movement from a visual consequence into a playable state.
Once an enemy is airborne, the fight is no longer a simple exchange between Dante and whatever is trying to kill him.
I can keep it there with gunfire, follow it upward, bring it crashing back down, or continue the sequence however I want (even when the available moves are relatively limited by the standards of later sequels).
We are so used to air juggling now that it is difficult to imagine how strange the idea must have seemed in 2001.
The original Devil May Cry still had Resident Evil all over it, from the fixed camera angles and castle setting to the puzzles, heavy doors, and long, uneasy stretches of silence between fights.
Then the battle music started and suddenly I could launch a demonic puppet into the air, shoot it repeatedly with Ebony and Ivory, and bring it crashing down with my sword.
I love how vulnerable the environment makes me feel compared with how much control the combat gives me.
Resident Evil had taught players to worry about ammunition, manage distance, and consider whether an enemy was worth engaging at all.
Devil May Cry gave Dante a pair of pistols with unlimited ammunition and encouraged me to see enemies as opportunities to experiment.
Air juggling made the journey to killing an enemy just as interesting as the kill, because there was always another attack I could try before it touched the ground.
There were quicker ways to kill a demon than keeping it suspended in the air, but few were as satisfying.
The satisfaction of controlling the entire sequence was what made Devil May Cry feel so different to me.
Better still, Devil May Cry never treated air juggling as a clever trick that had already served its purpose and instead kept expanding the idea until enemies became material for player expression.
Devil May Cry 3 expanded what players could do with that idea, adding weapon switching, combat styles, cancels, and a much wider range of possibilities during a fight.
Devil May Cry 4 introduced Nero’s Devil Bringer, which let players drag enemies back into range and continue attacking without breaking the flow of a fight.
Devil May Cry 5 then developed three playable characters around dramatically different forms of control, execution, and improvisation.
The combat became far more complex, but the same basic idea remained as enemies could be lifted from the ground, pulled out of their usual patterns, and made to move at the player’s pace.
The player could interrupt those assumptions and create a sequence that reflected personal skill and imagination.
It is also the idea behind the series’ obsession with grading how you fight. Devil May Cry does not only care whether the player wins.
It evaluates how the victory is achieved, encouraging variety and discouraging the repetition of a single safe move.
The style meter can seem like a cheeky bit of presentation, particularly once it starts shouting increasingly extravagant grades at the player, but it communicates a serious design priority.
Being mechanically competent is only the starting point, with fluency, risk, rhythm, and variation bringing the combat to life. Many action games allow impressive combinations, but Devil May Cry treats expressive play as the point.
The influence spread well beyond Capcom. Bayonetta, Ninja Gaiden, God of War, Metal Gear Rising: Revengeance, and numerous other action games developed their own approaches to launchers, juggles, cancels, weapon transitions, and performance scoring.
These games are not all direct copies of Devil May Cry, of course, but they belong to a design tradition that treats combat as a space for expression and gives players room to develop their own way of fighting.
Even genres that operate very differently have absorbed parts of that thinking.
For all the ways Devil May Cry has evolved, it still owes an awful lot to a bug that was too good to fix.
