Auto-Aim is a feature found in the Halo First-person shooters. It makes it easier for a player to target an opponent, shifting their focus from aiming to movement and strategy. Unlike other FPS games, Halo's Auto-Aim simply makes it easier to hit a target, rather than completely locking on to a target.
Halo's aim assist system is comprised of two parts: Auto-Aim and Magnetism.
Magnetism shifts the projectile trajectories towards a target. This is indicated by a red reticle. In Halo 1, the Auto-Aim system was very simple, as projectiles to traject toward the nearest part of an enemy. In Halo 2 onwards, the Auto-Aim system was enhanced to prioritize headshots. This made Face painting in Halo 2 onwards much easier. If a projectile's hitscan range is less than the auto-aim range, shot leading will be required, ALA Halo 3's Battle Rifle and Halo 1's Pistol, and many other weapons in the sandbox of these two titles.
Auto-Aim causes the player's camera to move with an enemy, slowing the look speed and dragging the player's look with an enemy's movement. Magnetism is only in effect while the player is in movement, or while the player is moving their aim. If the player is at a complete standstill with no look/movement input, they will not experience magnetism. This value is often larger than the Auto-Aim value, causing the player's movement to begin shifting before Auto-Aim is in effect; an exception to this rule would be an un-scoped Halo 3 Sniper Rifle, which will have a red reticle but no magnetism when pointed at an enemy.
