|Call of Pripyat|
Walrus is one of the ex-Monolith stalkers who somehow broke free of the influence that is controlling the Monolith and is led by Strider. They do not know what to do next and wishes to seek shelter before they are killed by the zone or by stalkers because of their Monolith uniforms.
Call of PripyatEdit
Gameplay-wise, Walrus has no significant story-wise impact and is only there to guard the camp where the rest of the Monolith deserters are holding up.
