Random Greatest Video Game Easter Eggs (103 items)

(#64) Elevator Disco Rave in Crysis 2
Not even a Nanosuit can provide these kinds of smooth moves. While trekking through the office building in the "Dead Man Walking" mission, you can uncover a lovely surprise: two C.E.L.L. assault soldiers boogie'ing their hearts out in an elevator car filled with strobe lights, fog, a disco ball, and thumping techno. Maximum Dance, engaged.
(#19) You Can Unlock All of the Bonds in Goldeneye

Rumor has it that when they first conceived Goldeneye, you could unlock all of the different James Bonds and could even play as alternate Bonds in the game's bonus levels. It's not clear why the mode was cut, though there was most likely a gamut of legal issues or a cranky Sean Connery.
Luckily, the other Bonds weren't taken out of the game, just made inaccessible. In 2004, fans made an awesome mod that finally allowed the lost Bonds to be used.
(#88) Insomniac Museum's Deleted Content in Ratchet and Clank: Going Commando/Up Your Arsenal/A Crack in Time
This one might seem a little too much like self-promotion, but the Insomniac Museums actually exist to show off content that the developers chose to cut from the Ratchet and Clank games. Usually only accessible at certain times of the day after you’ve 100% finished the game, you’ll find leftover items, art, and other features that Insomniac chose not to include in the game. We wish more developers found such cool ways to share stuff like this with their most dedicated fans.
(#26) Cloud Strife and Aerith Gainsborough Reunite in Final Fantasy Tactics
In Chapter 4 of Final Fantasy Tactics, you can follow a series of steps to open a time portal and get Cloud Strife to join your party. Doing so ultimately results in his encounter with a "flower girl" - Aerith - who is being harassed by thugs, one of which suggests she sell her body instead of flowers. Ick.
(#41) Put Wario on Mount Rushmore in Pilotwings 64
When it launched with the N64 in 1996, Pilotwings was known as the other game that came out alongside Super Mario 64. And Mario even found a way into Pilotwings by replacing George Washington among the Presidents on Mount Rushmore. But if Mario’s not your bag, secret seekers found out they could run into Mario’s face and switch the visage to Wario’s instead.
(#100) Secret Hall of Developers on "Dark Bride" Level in Serious Sam 3: BFE
All the Serious Sam games are packed to the gills with secrets, this is just the latest and highest resolution version of the series's most recognizable (and strangest) running joke. In the "Dark Bride" level, some tricky jumps can get you past a giant pond and through a nearby window. Once across, you're accosted by giant-headed martians with the developers' faces. Kill them. Kill them all.
