"New" map - de_dust2

Hello Blood Cubers, 

New map! Enjoy this blocky low-poly version of de_dust2.

I started the weekend learning how to use ProBuilder, and figured I'd try to make the map I've probably put the most hours into of any game. In a moment of distraction, I found myself reading about someone who 3d printed a model of de_dust. Which led me to find a low-poly minecrafty version of dust2 made by madexc. I was able to import it and add enemies throughout. Nostalgia abounds. 

I also added a main menu and fixed some cursor issues.
