Sheckley

Sheckley is a Resistance soldier who appears in the This Vortal Coil chapter of Half-Life 2: Episode Two.

History
Sheckley was assigned to an underground Resistance post outside of City 17, but attacks from zombies and antlions brought the number of troops there down to just him and a medic named Griggs. Sheckley and Griggs had very different personalities, as Sheckley was serious and Griggs was naive and light-spirited, though they still formed a team despite their differences.

When a Vortigaunt brought the wounded Alyx Vance down to the mines, Sheckley and Griggs protected them from antlion assaults. When Gordon Freeman arrived, Sheckley and Griggs briefed him on the current situation and helped him fend off Antlion assaults until more vortigaunts could arrive. Sheckley blamed Gordon for their troubles and implied in several statements that he was causing the trouble by killing Antlion Grubs.

Sheckley and Griggs stayed to protect Vance and the vortigaunts while Gordon and a Vortigaunt got an essence from nearby antlion caves. Afterward, they accompanied the Vortigaunts in hunting Advisors.

Personality
Sheckley is a no-nonsense character who is rather distrustful. He blames Gordon for the antlion attacks, suspects all technology available to them as easily made inaccurate and more easily broken.

Trivia
According to the Orange Box Prima Guide, Sheckley and Griggs are a reference to Abbott and Costello.
