Official Quakewiki Video - Quake - E2M2 - the Ogre Citadel

A tight building filled with numerous enemies that can easily tear down your health. Ogres in particular are deadly in this level, with them and Knights making up a large majority of the enemies this means every turn can injure the unwary player. Still, the Ogres make dealing with the Zombies in the water below easier. The water provides an alternative route (the route taken in the video) to using the Gold Door which leads to the raising platform near the end of the level. This means that the player can completely bypass the Gold Key by following the water.
