Hey everyone!

This is a pretty big update that includes a lot of bug fixes and a new feature that was requested recently.

I've also created a new gameplay trailer that shows more of the game!

• Added a weapon upgrade system.
  
• Added a teleporter that takes you to a hidden area of the game.
  
• Fixed some blockages in the Underground Facility map that prevented zombies from moving.
  
• Fixed some issues with the player's shadow.
  
• Fixed an issue where the player could jump out of the map in the Underground Facility map.
  
• Removed water collisions in the Underground Facility map.
  
• Fixed the boss spawn in the Underground Facility map.
  
• Increased the time for the zombie spawn rate so zombies spawn a little slower.
  
• Added a notification for when the random weapon box teleports.
  
• Fixed an issue that showed the user the wrong price for certain traps and perks.
  

Thank you all for your continued feedback and support!
