10 More Video Game Easter Eggs Nobody Understands

10. The Hidden Marine - Halo: Combat Evolved

The Halo franchise is no stranger to oddball, head-scratching Easter eggs, and the original game features a peculiar secret that continues to baffle over 20 years later.

At the start of the level "343 Guilty Spark," players can cause a glitch by throwing a plasma grenade while onboard the Pelican. Doing so will allow you to stay on the ship as it flies off, eventually resulting in you being dropped from the Pelican outside of the level's bounds.

Wander around in the foggy abyss for a while and you'll eventually find a solitary Marine, modelled after infantryman Private Mendoza, standing eerily still. If so inclined, you're free to shoot and kill him, perhaps in an attempt to free him from this ominous prison.

In 2011's Anniversary remake, the Easter egg remains due to the remake being built upon the original game's foundations, except this time the Marine is hilariously positioned behind a tree, making him a little trickier to spot.

It's been theorised that Bungie may have wanted to load Mendoza's character model at the start of the level before he appears later on, and the out-of-bounds area of the map was a safe way to do so while concealing his presence from players.

But of course, players will always find a way to get behind the curtain and see how the sausage is made.
