This guide will provide you with the four best ways to use Repulsor.
1. You can use it to knock enemies off the map and into wall splatter kills.
2. You can also use Repulsor to reach higher positions and heights that you cannot achieve without the Repulsor.
3. To change the trajectory of your grenades/make them detonate in a specific area instantly.
4. To throw weapons at your teammates.
Halo Infinite has a drop weapon button; you may have to bind it in the keyboard/controller setting.
