Laszlo

Laszlo is a very intelligent member of the Resistance who is considered by his close friends to be the finest mind of his generation. He appears only in the Sand Traps stage of the game.

Half-Life 2
Along with his friend Sandy, he moved through the beaches (possibly retreating from Lighthouse Point or another Resistance base) to the Vortigaunt Camp in order to get some pheropods so that antlions would leave them alone. However, Laszlo was wounded by antlions and stuck on the sand, putting him in a difficult situation, because he was badly injured and moving would cause antlions to rise and attack him. When Sandy saw Gordon Freeman approach, Laszlo (by reflex) looked up to see who was coming, and the antlions were alerted. Four antlions set upon him and tore him apart before Sandy and Freeman could defeat them.

After killing them, a very aghast Sandy grieves over Laszlo, then tells Freeman not to feel guilty over his death because it is not his fault. He also tells Freeman to just move on and leave him, because there is "something he has to do". It is unknown what this is, but if one returns later, Laszlo's body will remain, but Sandy will have left.

Trivia
His character model was originally meant to be for a character named Samuel, who would ride with Gordon on the Razor Train to City 17.

He is a reference to Val Kilmer's character in the 1985 film Real Genius.
