Oko are creatures that are released from an organ on Ustanak's back. Insect-like in appearance, their erratic flight patterns are more indicative of bats. Oko is derived from the Serbian word for ''eye."

It was found by Jake Muller and Sherry Birkin while in an underground cavern in Edonia, trying to avoid the Ustanak.

Biology

As their namesake implies, they act as the eyes for the visually impaired Ustanak, but ironically rely on ultrasonic waves to track their prey. They're very small and mobile, flying on two wings that closely resemble those of a bat. Their sense organs are shared with Ustanak, and when a target is found, they emit a flash and flap their wings at a level only Ustanak can detect. (The mechanism behind this shared sensory perception is unknown.) Their ultrasonic waves cannot pass through walls and other barriers.

The primary feature is several glowing tumors on their body. When they are solitary and away from danger, the tumors are colored a bright blue. However, when they sense something nearby, the tumors suddenly turn red and they let out a loud, piercing shriek akin to a siren.

Gameplay

These bat-like creatures work in advantage to the Ustanak in the underground cavern of Edonia while Jake and Sherry are trying to avoid him. They project a bright blue color from the tumors on their body when left alone, but if anyone gets within range of the blue light, the creature will take notice. It will react by shrieking - alerting the Ustanak in the presence.

Strategy

Shooting these creatures is not recommended as the sound will draw the attention of the Ustanak while it is hunting for you. Wait for an opening, observe its moments and run up behind it while its light is turned away. You'll be prompted for a contextual attack that will instantly smash and kill the creature. Running does not alert this creature to your presence.

Shooting is possible, but as you have only two chances of hiding while the Ustanak is hunting you, it is highly recommended to use a powerful gun to kill the monster with one shot, such as the Elephant Killer or the sniper rifle.
