• propses to build level
• 12 turrets (some of them have walk animation)
• modular pipes
• .sbsar (substance designer) materials, so you can change and have any colors for levels and propses. (P.S. to use .sbsar materials in unity 2018.1 you need to install a suitable third-party external importer from the Asset store.)
