There are free shooters in the App Store – FastHit VR Review

and most of them are better than this game. The gun constantly shoots even when you're not aimed at an enemy. Which means you hear a looping sound of a gun shooting constantly… Not good. It drives you crazy. If the gun only shot when aimed at the enemy I would give it one more star but as it is it's a headache waiting to happen.
