Half-Life 2: Episode Two (Video Game)
A DHARMA logo is hidden in Half-Life 2
The Numbers are hidden in Half-Life 2
There are two known Easter eggs in the first person shooter video game Half-Life 2: Episode 2 (Source: Kotaku.com)
In Half Life 2: Episode Two there is a DHARMA-like logo with three white trees hidden on a wall. This is referring to the "White Forest Station" where the player is headed. This is obviously not a DHARMA Station, and any other reference to Lost is made elsewhere.
There is a CRT monitor displaying the Numbers in a blocked hidden room in the second level. Switching on the designers comment at this place, you are told that the valve guys promised the directors from Lost to put it there after there had been references to Half Life in Lost; this happened in "The Greater Good," where the terrorists Sayid was spying on were playing Half-Life. A shotgun shot was heard, and the player said, "Crap, out of ammo." Another terrorist, watching the game, told the player to use the crowbar, to which the player responded that the crowbar only worked on zombies.
The Half-Life 2 series also has a main title screen that is very reminiscent of the menu screens for the Lost DVDs.
