 On Frohman 's arrival , Ravenholm is depicted as a peaceful , bright , and cheerful place devoid of any Combine elements , but " terrorized " by Father Grigori . After adjusting , Gordon becomes accustomed to the town , but unintentionally discloses the town 's location to Dr. Breen , who immediately orders his forces to " bomb the shit out of them " . The town is fired on with headcrabs , killing many and turning others into zombies . Frohman himself is attacked by a headcrab and turns into a zombie too , yet retains his free will ; and after a while his headcrab dies of malnutrition , which is attributed to his lack of intelligence . With Father Grigori 's help , Frohman escapes Ravenholm , now the zombie @-@ infested nightmare seen when Freeman visits it in the game , and presses on to Nova Prospekt . After surviving several more hazards , he reaches the coast . Here , after passing the final resistance base and an Antlion @-@ infested beach , Frohman encounters an Antlion Guard , which is killed by a Vortigaunt , an alien race helping the humans in the game . This allows Frohman to retrieve bugbait from the dead creature , with which he can control the Antlions .
