Magnetism

This article is about camera magnetism. If you were looking "bullet magnetism", a related concept, see aim assist.

Magnetism is a gameplay system in place in the Halo first-person shooter games designed to help players target enemy combatants more easily. It is only enabled for players using controllers - those on mouse and keyboard are not affected. Magnetism slows the player's turning speed while an enemy is within a certain radius of the reticle, making it easier for the player to make fine-grained adjustments to ensure they hit the enemy with their shots. It also partially accounts for any movements the enemy makes, for instance if they're strafing, by moving the camera subtly so that the reticle ever so slightly tracks the enemy.

The goal of magnetism is to make aiming with a controller easier, combining with aim assist to make the use of controllers for a first-person shooter more accessible. However, aim assist, unlike magnetism, also applies to players on mouse and keyboard.
