Red Letter Day

Red Letter Day is the second chapter in Half-Life 2. We meet up with Dr. Kleiner, who's looking for his missing headcrab pet, Lamarr, and Barney Calhoun to test out the teleporter. Alyx Vance successfully teleports to Black Mesa East where her father, Dr. Eli Vance and Judith Mossman awaits.

Gordon is not as lucky. As he's teleporting through, the teleporter is destroyed. The event can be felt far away, and Gordon has to escape.

Trivia

• Red Letter Day consists of two maps; d1_trainstation_05 & d1_trainstation_06.
• In Kleiners lab, a mini-teleporter can be found. If you teleport enough things through it, it will break.
