A hidden The Last Guardian Easter egg is one of the few new additions of the Shadow of the Colossus is PS4 remaster.
Unlocking one of the game's Trophies, Boon of the Nomad, it's surprisingly close to the start of the game, allowing you to find it within five minutes of the opening cutscene wrapping up, if you were particularly keen to track it down.
If you're after more help, our Shadow of the Colossus walkthrough, guide and tips provides strategies for every Colossus.
Where to find The Last Guardian Easter egg in Shadow of the Colossus
First, head to the Shrine of Worship (the temple where you start the game in the middle of the map) and take your horse Agro in a south-west direction.
You'll see some thin towers in the distance, and some rocks on the right. You'll want to turn into here, where you'll find the entrance to a forest.
Just a few moments into the forest, you'll notice some ruins through the trees to your left.
This is one of the game's many Shrines, which you can pray at to recover your health.
From here, continue going in a south-westerly direction, over a stream, until you come across a cave entrance in the ground.
Here's the specific location on the map - it's in segment E5, with the forest and its river represented by the squiggling line.
Head into the cave. At the far end is a barrel surrounded by butterflies.
Seem familiar? This is just like those you've seen in The Last Guardian. Throwaway Easter egg, or subtle sign there's more to connect these games than meets the eye?
For more helpful stuff on Shadow of the Colossus, our Shadow of the Colossus walkthrough and guide can help you hunt down and kill every colossus, including the tricky third Colossus, eighth Colossus, ninth Colossus and eleventh Colossus. We also have explainers on all Agro tricks, how to find and use lizards and fruit and Enlightenments, and where to find a The Last Guardian Easter egg and all Shrine locations.
Either way, as soon as you get close enough, the Boon of the Nomad Trophy will appear. Done!
If you are having difficulties with the exact location, this video shows the complete route from the starting shrine to the cave:
Why is it named Boon of the Nomad, you might be wondering? It's named after one of the leading theorists in the Shadow of the Colossus community, as confirmed by developer Bluepoint Games on Twitter:
This Easter egg is not the only new addition to Shadow of the Colossus on PS4 - it looks like there's a new mystery to solve in the form of additional collectables, one of which can be found in this very cave.
Where to find Ico Easter egg in Shadow of the Colossus
Fancy tracking down another Easter egg? This time it's one connected to Team Ico's first game, Ico.
Head to the beach on map segment B5, and at the end against the cliff wall is a watermelon in the sand.
At first this is a seemingly random fruit to be found, but as the above video by Max Derrat explains, it's actually a reference to Ico's alternative ending, as well a nod (and not necessarily a confirmation) to fan speculation that this beach is the one and the same location.
