Gonta(Also called Gaunt in some translations) is a hunter Stalker you first encounter in the Skadovsk medic's office with two of his hunter buddies, one of them badly injured. After a quick dialog with Gonta the player will learn that a Stalker named Magpie was supposed to help them in a Chimera hunt but instead ran away with their loot. Gonta gives player the quest of finding him, and later(if the player tells him about Flint or that Daniel was killed by Tremor) also offers to help him in finishing the wounded Chimera.
