There's no shortage of quests if players decide to go off the beaten path in Stalker 2: Heart of Chornobyl. Players encounter one of these random quests while exploring the Chemical Plant region, which involves taking down a powerful mutant. Although you'll be facing a Pseudogiant as part of this quest, Vadyk Firecracker will give Skif the coordinates to a stash that contains some valuable loot and a weapon, that makes it worthwhile.
