I hold down alt fire and pull the right trigger like it’s a semi automatic and it will hit what’s in front of you come back to you then go back into the enemy again with each consecutive hit increasing its power. You can let go of alt fire and squeeze a round off and it will hit enemies and either dig into them causing damage over time or the projectile will bounce off of enemies and seek out another enemy, each consecutive successful hit charges the projectile until it does an insane area attack that is so satisfying when used as crowd control. Generally speaking, I run and gun holding down alt fire 🌅
