Blockout - Zavod

This block out is made for a test task for a first-person shooter in the post-Soviet post-apocalypse setting. I made it in three evenings, completing the main tasks: 
• There should be tutorial, the main part, and the boss arena. 
• To get into the arena with the boss, you need to use at least two levers/buttons. 
• There is no need to do NPCs. 
• Three stages of the boss arena.
