Unity Asset Store – Spider Character Spiders Pack v3.0

Spiders Pack features three fully animated Spider characters. Resize in editor to create Small, Medium & Large spiders -- each one is designed to be different enough from the others so players know they're unique.

Further, customize the Textures with the Substance Painter source files to create the prefect spiders for your game.
