Of everything in the FPS script, Auto-Tracking with Headlock generates the most skepticism — usually phrased as "how can a dongle track enemies it can't see?" It's the right question, and the answer explains both why the mod works and why it has a hard ceiling. Let's take it apart.
The Constraint That Shapes Everything
A Cronus Zen sits between your controller and the console. It reads controller input, modifies it, and passes it on — the console sees a standard controller. What it cannot do: see your screen, read game memory, or receive any information about where enemies are. Any mod claiming otherwise on a Zen is lying about the hardware.
So how does tracking work with zero knowledge of the target? By borrowing the one system that does know where the target is: the game's own rotational aim assist.
How Auto-Tracking Actually Works
When your crosshair is near an enemy, the game applies rotational aim assist — it rotates your view slightly to follow the target, and it scales that help based on your stick input. This is the hook. Auto-Tracking continuously shapes your right-stick output with structured micro-movements that do two things:
- Keep rotational assist fully engaged — same principle as Polar Aim Assist: assist only works while sticks are active, so the script guarantees activity.
- Lean into the assist's corrections — the injected movement sweeps through directions in a way that lets the game's assist "catch" and amplify the component pointing at the target. Input toward the target gets reinforced by the game; input away gets damped by the same slowdown mechanics. The net effect biases your aim toward whatever the game is already assisting on.
Notice what's doing the actual targeting: the game. The script never knows where the enemy is — it creates the input conditions under which the game's own tracking works hardest. That's also why the result looks natural in killcams: it is the game's aim assist, running at full duty cycle.

What Headlock Adds
Rotational aim assist tracks center mass — that's where the assist bubble is strongest, and left alone, your crosshair settles on the chest. Headlock layers a small, persistent vertical bias on top of the tracking so your aim point rides at head height instead. Chest damage is fine; head damage wins fights faster in every shooter that has damage multipliers, which is all of them.
Two practical notes on it. First, the bias is small by design — it nudges, it doesn't yank, because a hard upward pull would fight the game's assist and feel awful. Second, it interacts with anti-recoil: recoil pushes your aim up, anti-recoil pulls it back down, and Headlock defines where "down" settles. Tuned together (the script handles this internally), your spray converges at head height rather than sliding to the stomach.
The Honest Ceiling
Here's where I tell you what this mod won't do, because the marketing elsewhere in this space is out of control:
- No acquisition. If your crosshair isn't near a target, there's no aim assist to amplify. You still have to get on target yourself; the mod maximizes tracking after that.
- No wall tracking, no lock-on. The game's assist disengages when a target breaks line of sight, so the mod's effect disappears with it. Anything else would require reading game data, which the hardware can't do.
- Assist-dependent. In a mode or game with controller aim assist disabled, Auto-Tracking has nothing to lean on.
If you understand those limits and still expect a real difference in how sticky your tracking feels through strafes, slides, and jumps — that's exactly the right expectation.
Setup and Pairing
Auto-Tracking with Headlock ships enabled in the 
FPS script and works across Call of Duty, Battlefield, and other shooters. Two settings on your side matter most: keep your minimum deadzone low so the micro-inputs reach the game (the deadzone guide explains why), and use the game's default aim assist type, which is what the mod is built around — the Warzone settings guide has the full recommended sheet.
