A large portion of Avenged Sevenfold's highly anticipated new song has surfaced online and fans are buzzing with excitement. The track, which was made in collaboration with Call of Duty: Black Ops 4, is featured in a yet-to-be released trailer for the game. It was shown at a private event, but a Reddit user shared a phone-filmed footage of the clip on the official Avenged Sevenfold subreddit.

Avenged recently teased the song in a new video that recapped their European festival run earlier this year. The band announced they were working on a song for the video game in May. Bassist Johnny Christ said they had written it and were in the middle of the recording process at that time. He claimed the track is "a little bit of a departure from what I think our fans would expect."

Avenged previously wrote a song for Call of Duty: Black Ops 2, titled "Carry On."  An official release date has yet to be revealed, but fans are expecting it to drop any day in the near future. You can listen to the roughly 16-second teaser below. Call of Duty: Black Ops 4 will be released on Oct. 12, 2018.
