The Star Wars Battlefront Proximity Bomb power up is motion sensor bomb that you can plant anywhere that will be triggered by enemy movements. You can stick these weapons on the ground, on walls, trees, or anywhere else you can possibly reach which makes these quite fun to use.
When an enemy gets close enough to the Proximity Bomb it will begin to make noise as it prepares to detonate, but if the enemy backs off rather quickly, the bomb will go back into its hibernation mode. These are great to use on game modes like Cargo, or Drop Zone, where you can defend your territory or cargo well after you have left.
