IO interactive recently released the Halloween Trailer of "Killer 2". Killer 47 will sneak into Hawkes Bay in New Zealand as a pumpkin skull to complete the assassination contract. The video address is the same as the content of the ontology. Players can unlock new tools by completing the challenges and achievements in the game. This Halloween event brought players new equipment, including "tactical diving suit" and "bat sword in hand" props. It is reported that this Halloween activity update will be launched on October 22, and is open to all players with "Killer 2" (including downloading the free novice bag).
