We've all seen the rise in popularity of open world games, with many of the our favorite titles of all time using this sprawling, exploration-based map format.
Whether you're gliding around in the influential Legend of Zelda: Breath of the Wild or playing cowboy in the critically acclaimed western masterpiece, Red Dead Redemption 2, their open-ended environments and quests lead to an excellent level of replayability, proven by something like Skyrim's enduring popularity. We've even witnessed franchises that previously weren't open world adopt the format, such as Halo, Metal Gear Solid and the Witcher.
To that end, secrets and easter eggs have always been prevalent in video games, with hidden items and areas scattered throughout levels and environments that many of us spend hours hunting down.
In an open world these are even more difficult to find, especially thanks to the increased scale present in many modern titles. Whether it's a nod to another game, a ridiculous usable item or a creepy random encounter though, developers love to pack in plenty for you to discover.
Let's take a look at the best, weirdest or creepiest open world game secrets you probably never discovered.
10. Giant Sandwich - Halo Infinite
We finally got our hands on Halo Infinite at the end of 2021, after it was delayed by an entire year and was met with near universal acclaim for both it's open world campaign and free-to-play sandbox multiplayer offering.
The vast open design of the latest Halo is new to the series and we have enjoyed exploring every inch of the world, which features collectibles, Easter eggs and side activities scattered throughout. These range from armor lockers that provide aesthetic items for Infinite's multiplayer to spartan cores which can be used to upgrade Master Chief's arsenal of new abilities.
All of us can agree that the grappling hook in Halo Infinite is a ton of fun, allowing even greater traversal and movement options to navigate the sprawling, vertically complex formations of the map. This also allowed developers many opportunities and locations to cram in many secrets.
One secret which baffled many players when they stumbled across it lies beneath the surface of Zeta Halo, in a hard to find cave formation. A giant sandwich is sitting in the middle of the cave, surrounded by grunts who are seemingly worshipping the enormous snack.
Why this is present in Infinite is anyone's guess, with it probably being an in-joke at 343 industries.
