Recently, Call of Duty: Warzone teased gamers with the entire unveiling of Call of Duty: Black Ops 6 by adding a secret submarine to the Rebirth Island area. In Call of Duty: Warzone, players that locate and enter the submarine may also be able to fulfill a specific task and receive special loot based on the upcoming Black Ops release.

Call of Duty: Warzone is a sequel that was released more than four years after the first game. It features a number of maps, frequent balance adjustments, and a ton of new upgrades and material every year. Warzone has also been utilized as a set to preview upcoming Call of Duty games in recent years. For instance, prior to Call of Duty: Modern Warfare 3's release in November 2023, Warzone hosted exclusive events and trailers. A new teaser video for Warzone Season 4 confirms that Frank Woods will make a comeback in Call of Duty: Black Ops 6. Before the game comes later this year, Warzone gamers can also acquire Black Ops 6-themed treasure through new in-game challenges.

A video of Warzone player B23 accessing the hidden submarine—which is situated close to the Bioweapons Lab at the map's northernmost point—was posted on Twitter by CharlieIntel. After entering, players will find a typical loot stash close to the entrance, but continuing within the submarine reveals a communications room. In this area, you can finish the last Black Ops 6 in-game task by snapping the picture on the adjacent evidence board. The Warzone player receives the new "The Truth Lies" execution upon completing this challenge, which alludes to the live-action trailer for Black Ops 6.

The Call of Duty community has responded largely positively, and many Warzone gamers are looking forward to the complete revelation of Black Ops 6 and the upcoming improvements that will follow the game's release. Nevertheless, after playing multiple rounds, the submarine is still not spawning for certain Warzone gamers, leaving them perplexed and angry. It's probable that specific requirements must be fulfilled before any player can enter, as several users have noted that the submarine's clasp was closed when they discovered it on Rebirth Island.

The hidden submarine is a fantastic addition to Rebirth Island since it makes Black Ops 6 more exciting and gives Warzone players something for their curiosity. Call of Duty fans should be in for an exciting summer and later fall with the impending release of Black Ops 6, as well as the start of Season 4 of Modern Warfare 3 and Warzone.
