Call of Duty: Black Ops 4 developer Treyarch has confirmed the latest limited-time event coming to the game's Blackout mode.

"It’s true, Ambush is coming soon in Blackout as our next limited-time mode in Blackout – just not quite yet," wrote the developer.

The mode was originally leaked through the Call of Duty companion app before being spotted by a keen-eyed Redditor.

Details pertaining to Ambush's rules and gameplay are yet to be confirmed.

Treyarch also confirmed that the current Down But Not Out limited-time mode will remain live for "a couple of weeks on each platform" before Ambush takes the stage immediately after.

DBNO started on PlayStation 4 earlier this week, and is set to hit PC before the week's end.

Black Ops 4 Blackout is the franchise's answer to the Battle Royale craze that has dominated the industry.

In Gameplanet's Call of Duty: Black Ops 4 review, Baz Macdonald scored it 9/10, especially praising the level of execution and polish evident in the game's Blackout mode.
