Didn't BioShock Infinite have a drake Easter egg?
My friend said he say one when he was playing through the game, but I don't have it so Idk if its true
idk, never played bisohock, but there was one in god of war ascension: a trophy for collecting all of the artifacts in the game was titled: "no drake, you can't have these" lol
You can meet a guy wearing familiar looking gogles who is eating a wumpa fruit and reading Drake's journal. Bam 3 easter eggs in one relating to ND's main franchises.
Maybe they can do different chapters with scenes referencing different UC games (I didn't play Jak and Crash )
UDF: Ali's idea is good. The zombie thing can be wearing Eddy's vest and his torn shirt. Near where he was, you can grab a gold gun.
UC2: The "Jeff getting attacked by zombie Zoran" idea I stated a few pages back.
UC3: A blonde and some dude in a green french sweater is getting attacked by a zombie in a red button-down shirt and a zombie in a suit vest. You can opt no to help them, like the UC2 idea.
They should all be a side-thing, and when you find all of them you get the trophy titled "In Uncharted Territory".
