The Multiplayer Select Screen Easter Egg can be found in Halo: Combat Evolved.
When you select "edit gametypes" on the Halo: Combat Evolved multiplayer select screen, an image of a Spartan appears to the right of the multiplayer select screen with little captions pointing to various parts of his body. Upon closer inspection, these captions are actually Easter Eggs:
- Sometimes I give myself the creeps/Sometimes my mind plays tricks on me (this is a lyric from the Green Day song "Basket Case.")
- Hydraulic suspension thigh pads with cool Kevlar crap.
- Action/Reload one-way flexible joint system.
- UV protectant: Sun visor for protection from elements.
- UV protectant: Sun armor for protection from elements.
- All your base are belong to us
- Directional Lock MJOLNIR Cyborg Dealer Parts
These captions are also present in the PC version.
