While Blacklight is a shooter first and foremost, its robust customization system gives it an almost RPG-like quality. You can customize your character's appearance, changing out their armor to give them more health or faster running speed. Additional equipment slots help you flesh out your character's capabilities, tailoring them to your particular playstyle.
Although this is an old game. It's still a great one and free on PS4! I recently started playing and it's definitely a great way to pass the time!
