I don’t mean a “lost island” like it’s pretty hard to find, I mean that the dev team from Just Cause 2 literally put in the island from Lost in the game, that causes your plane to crash when you get near it.
That would be cool enough as is, but hunting around the island itself will lead to the discovery of the hatch from the show. Sadly, beam of light and John Locke are sold separately.
I’ve no idea what this game is, or why this guy can parachute after jumping around on the ground, but it is one of the cooler easter eggs I’ve seen in a game. Check it out, and skip to the end after the plane crash for the hatch.
