The classic lock-on is simple: hold a button, and you stick to an enemy. Directional inputs are relative to the camera. Forward is always toward the locked-on target.
The Definitive Edition didn’t just add a lock-on toggle. It added a Hardcore Mode that rebalanced the entire combat system around manual targeting, enemy placement, and取消了 the color-coded enemy immunity (another fan complaint). In the credits of the Definitive Edition , under “Special Thanks,” there was a single line: Simon “Vergil’sWard” Tarkowski – For showing us the way. Simon never made another major mod. He went on to work as a gameplay programmer at a studio in Warsaw, where he now builds combat systems for indie action games. He still plays DmC occasionally, with his own mod installed, of course.
He would try to pull off a classic combo: launch an enemy with High Time, air-juggle with Osiris (the scythe), then switch to Arbiter (the giant axe) for a downward slam. But without lock-on, his directional inputs would betray him. He’d go for a Stinger (the forward-lunge) only to slash at thin air because the game thought he wanted to hit a different target. He’d try to shoot a specific witch in the back, but Dante would waste bullets on a fodder enemy in front.
Simon realized he couldn’t just “add” a lock-on. He had to suppress the auto-aim, create a new variable ( bIsLockedOn ), and then manually override every single melee and gun input to read from that locked target’s position instead of the camera’s forward vector. Dmc Devil May Cry Lock On Mod
But the most unexpected consequence was the effect on DmC: Definitive Edition . Later in 2015, when Ninja Theory released the remaster for PS4 and Xbox One, lead designer Dominic Matthews was asked about lock-on in an interview. He paused. “We heard the fans. Loud and clear. The mod on PC… it showed us what was possible. It showed us what players really wanted.”
The mod did more than add a button. It transformed the game. Suddenly, style-switching between Angel and Demon weapons became surgical. You could lock onto a flying Harpy, pull it down with Angel Lift, launch it, then switch to the shotgun (Revenant) and fire a charged shot directly upward, all while staying locked on. The “Stylish!” rank wasn't just a meter anymore; it was a promise you could keep.
Then came the UI. He needed a visual indicator. The original game had no lock-on reticle. So, he found the enemy health bar widget and injected new code. When you locked on, a pulsing, angular red diamond—a direct homage to Devil May Cry 3 ’s lock-on icon—would appear over the target’s head. The classic lock-on is simple: hold a button,
On the DmC subreddit and the Devil May Cry forums on NeoGAF, the debate was cyclical. “You just need to learn the new system,” casuals said. “It’s not DMC,” the veterans replied. “Modders will fix it,” someone always said, with a mix of hope and sarcasm.
In its place was a soft, contextual “aim assist.” You faced a direction, and Dante would automatically slash or shoot the nearest enemy. For the hardcore players who had spent a decade mastering jump-cancels, enemy-switching, and precise directional inputs (forward-forward for Stinger, back-to-forward for High Time), this felt like a betrayal. It was like giving a race car driver a steering wheel that steered itself. The game was good, many admitted, but it wasn't Devil May Cry .
That’s when Simon, a computer science student with a minor in game design, cracked open the game’s Unreal Engine 3 files. He knew UE3—he’d made small maps for Mass Effect 3 and tweaked weapon stats in Batman: Arkham City . But this was different. This was rewriting core input logic. For three weeks, Simon lived a hermit’s life. He used a tool called UE Explorer to decompile the game’s scripts. He found the input handler: DMCPlayerInput.uc . Inside was a nightmare of contextual logic. The function GetNearestEnemy() was king. It would calculate vectors, angles, and distances, then override the player’s intent.

He didn’t cheer. He just smiled, saved the file, and typed a single post on the Devil May Cry subreddit: I fixed it. Proper lock-on mod for DmC. Download inside. The Fallout and the Revelation The response was apocalyptic in the best way. Within 24 hours, the post had 5,000 upvotes. Modding sites like NexusMods and ModDB crashed under the traffic. Gaming news outlets—Kotaku, PC Gamer, Rock Paper Shotgun—ran headlines: “DmC Fan Mod Adds Classic Lock-On, Fixes the Reboot’s Biggest Flaw.”
The lock-on mod became a symbol. It proved that in the age of corporate focus groups and design-by-committee, a single dedicated fan with a hex editor and too much time on their hands could change the conversation. It didn’t make DmC a perfect game—the story was still messy, and the original Dante’s character remained divisive. But it made the combat undeniable.
The biggest hurdle was the Angel Lift and Demon Pull. These were context-sensitive pulls and grapples. With a lock-on, they needed to work at any range, not just on highlighted enemies. He spent four sleepless nights rewriting the targeting function for those two abilities alone.
In the winter of 2013, the action gaming world was a battlefield. Ninja Theory’s DmC: Devil May Cry had just been released, and the fires of fan outrage burned hotter than any demon’s inferno. To the purists—the disciples of the original series created by Hideki Kamiya—the new game was an apostasy. Dante was no longer a cool, silver-haired, pizza-loving icon; he was a chain-smoking, lank-haired punk. But the deepest cut, the one that drew the most blood, was the combat. The lock-on mechanic—a sacred, immutable pillar of the “character action” genre since Devil May Cry itself defined it in 2001—was gone.
