Recent teases from Call of Duty give new hints at what players can expect from Warzone's  Vanguard reveal event. The Call of Duty blog reveals that "a new kind of weapon" is making its way toward Warzone's Verdansk map. The ominous message suggests that Warzone players will be facing a mysterious new threat when they enter the battlefield on Thursday. The Call of Duty Twitter has shed further light on the event, explaining that players will earn exclusive rewards for partaking in the Vanguard reveal. New weapon and knife blueprints, a bike skin, and a cosmetic timepiece will be among the "care package" spoils.

For those familiar with the Call of Duty franchise, the  Vanguard tie-in event should come as no surprise. The always-evolving Call of Duty: Warzone was used to reveal Black Ops Cold Warand it appears that Vanguard will be also shown in the battle royale before the two inevitably integrate. Rumors suggest a massive Warzone map will launch alongside Vanguard, taking players from Verdansk to a huge swathe of World War II-era battlefield.

The coordination between Warzone and other Call of Duty titles has created a more or less seamless transition between new installments in the series. Just as the battle royale shooter tied into Black Ops Cold War, the in-game event will soon introduce players to the world of Call of Duty: Vanguard. With an unsettling new foe to face off against and brand-new rewards to earn, Call of Duty players will likely show up in droves into the Vanguard reveal event this week.
