Expanded Aim Assist

Expanded Aim Assist improves Gatekeeper's built-in controller assistance, enables it for keyboard and mouse and melee characters, makes target tracking yield to deliberate player input, and corrects the offset between the crosshair direction and the actual projectile origin for supported ranged primary attacks.

Features

• Improved controller aim-assist coverage and tracking.
• Keyboard-and-mouse aim assist using Gatekeeper's existing target-selection rules.
• Existing crosshair lock and pull enabled for Nidum, Bastion, Void Model, and Maverick without changing their attacks.
• Native AIM ASSIST toggle in the Keyboard and Mouse settings menu.
• Input-scaled tracking: normal assistance at low input, progressively less pull during deliberate movement, and near-zero pull at strong input.
• Configurable mouse-only held-target break radius in screen pixels, defaulting to 400.
• Configurable acquisition range, sphere coverage, tracking speed, and controller break radius.
• Crosshair/projectile-origin correction for the ranged primaries of Aegis, Hybrid, Pandora, Tech Hunter, and Mediator.
• Preserves Gatekeeper's target validation, excluded enemies, line-of-sight checks, target priority, camera ray, and ability placement.

Mouse target release

During strong mouse input, the existing held-target loss check measures from the physical cursor to the current target. Input Scaling.MouseHeldTargetBreakRadiusPixels controls the required screen-space distance directly; the default is 400 pixels. This setting does not alter controller target retention or controller attenuation.

When the mouse settles, Gatekeeper's native acquisition and prioritization resume. The mod does not clear targets manually or introduce a separate target-selection algorithm.

Crosshair correction and close range

For supported cursor-aimed ranged primaries, the mod corrects parallax between the crosshair ray and the projectile's actual origin. At a root-plane range of 3.25 world units or less, correction returns Gatekeeper's unmodified native direction. Beyond 3.25 units, the proven projectile-origin correction is used unchanged.

The hard close-range cutoff can look slightly unusual extremely close to the character, but it prevents pathological close-range misses while preserving medium- and far-range correction exactly.

Configuration

Launch the game once to generate BepInEx/config/com.prom.gatekeeper.aimassist.cfg. Important settings include:

• General.EnableForMouseKeyboard
• General.EnableForMeleeCharacters
• Input Scaling.EnableInputScaledAssist
• Input Scaling.MouseFullAssistBelow
• Input Scaling.MouseZeroAssistAt
• Input Scaling.MouseHeldTargetBreakRadiusPixels (default: 400)
• Input Scaling.ControllerFullAssistBelow
• Input Scaling.ControllerZeroAssistAt
• Projectile Correction.EnableProjectileOriginCorrection

Diagnostic logging is disabled by default. The in-game Keyboard and Mouse AIM ASSIST toggle updates the keyboard/mouse setting immediately.

Installation

Install with r2modman or another Thunderstore-compatible mod manager. BepInEx IL2CPP is required and listed as a package dependency.

Known limitation

The mod expands Gatekeeper's built-in selection system rather than replacing it, so the native forward fallback does not guarantee strict whole-screen targeting in every situation.
