A map based off the Counter Strike map of the same name.
Bonus names (represented by a small square) are set by callouts as they are named in counterstrike, with sub bonuses (represented by a diamond) named after popular fan callouts.
"Dust2 is one of the most played maps in video game history. It's appeared in multiple versions of Counter-Strike and is considered by many players—casual and pro alike—to be nearly perfect, unassailable." -Nathan Grayson, Kotaku
It's from a Kotaku piece written by Nathan Grayson, that actually disects why such a perfect nap can harm the map making community for Counterstrike. I've made a couple maps there, and that made me appreciate Dust II so much more.
To my knowledge, there is No Dust I map on warlight.
