After finding two of the Stadium key cards, Call of Duty: Warzone players can use them to unlock rooms in Stadium itself. Players can then write down the ciphers and glyphs in these rooms to figure out the Stadium access code. Unfortunately, the code will change each round, so players will have to do this every time they want to get through these locked doors. Upon doing so, though, they can get the Enigma blueprint and they will also trigger a special event.

Upon completing the Warzone Stadium easter egg, fireworks will start shooting off outside. It’s a neat easter egg, and it will be interesting to see if the Warzone Season 5 update is hiding any more secrets for fans to discover.

While some fans may be excited by this Stadium easter egg, others may be disappointed. Initially, Call of Duty: Warzone fans believed that this Stadium easter egg was actually a teaser for Call of Duty 2020, rumored to be titled Black Ops Cold War. Leakers have been saying for months that the Call of Duty: Black Ops Cold War reveal will take place within Warzone itself, and so it made sense that Stadium’s secret rooms would be part of the reveal.

But while this Stadium easter egg in Warzone isn’t a part of the Black Ops Cold War reveal, it seems as though fans may not have to wait too much longer to find out more about the new game. Activision has sent mysterious crates to various publications suggesting that the Call of Duty: Black Ops Cold War reveal will take place on Monday, August 10. So it may just be a matter of days before Call of Duty fans can finally get their first look at the next game in the long-running franchise.

While they wait for the Call of Duty: Black Ops Cold War reveal, Call of Duty fans can continue exploring Warzone Season 5 for more clues and easter eggs.

Call of Duty: Warzone is out now for PC, PS4, and Xbox One.
