Star Trek: Elite Force 2 Easter Egg - Exomorph-Chess

This egg is located at the level which you are transported back to the Enterprise from the Romulan Base (where Gonzales had been killed).
Go to the Brig and enter the first cell. While facing the back wall, press your USE key. If you are in the correct cell and also facing the correct wall, a secret door will open.
Inside the secret room, you can find a golden ship. You can also see Picard and the Romulan general playing exomorph-chess :)
