[3-3] How do I select a skill level?

Learn how to select skill levels in Quake, including easy, medium, hard, and the hidden nightmare level.

When you start Quake and select New Game, you are presented with three hallways. The one on the left selects easy skill, the one in the middle selects medium skill, and the one on the right selects hard skill. Walk down one of the hallways and into the slipgate (a portal that transports you to another area). There is also a hidden "nightmare" level skill level. Its location is revealed in [9-1].
