All Adverse barrels on the FiNN completely change the gun, lowering its damage per shot but very drastically increasing its rate of fire - to levels unmatched by almost every other gun in Warzone. The time-to-kill is far better with an Adverse barrel than without.

Based on the real-world Stoner 96, the FiNN LMG fires 5.56 ammunition at a relatively low rate, making it a very controllable alternative compared to other LMGs in Modern Warfare and Warzone that fire larger bullets much more quickly.

Not really. Jason Voorhees was more likely inspired by several disturbing incidents/killers than one specific one. In fact, (ANCIENT SPOILER ALERT) Jason's mother Pamela was the actual killer in the first film.

In Friday The 13th (1980), Pamela Voorhees was responsible for the murders at Camp Crystal Lake. In 1957, her hydrocephalic son, Jason, drowned as a young boy in the lake of Camp Crystal, while he was being bullied by most of the other campers.
