The Marauders/Bandits at the end of the road on Campaign mode despawn if you walk off too far to the left and then never respawn again for some reason?
Also the bullet resistant one should have some blood maybe to show off that he is getting damaged? Because right now it looks like he takes no damage at all because of the sparkles. He does die from bullets but the lack of proper visual cues on him getting damaged makes it kinda confusing.
