If you've wondered where legendary Counter-Strike map Dust2 has been since it left competitive matchmaking in February, here's the answer: Valve has been rejigging it. Following similar revamps, an "updated and refined version" of Dust2 will be available for testing in the next CS:GO beta depot.
Valve has yet to publish anything elaborating on the updates and refinements, though they did tweet out the picture you can see above.
...and that's about all we know at the moment, but if you want an idea of how significant Dust2 has been in the history of CS:GO, Evan spoke to some key CS:GO mapmakers in 2015 about its import. You can see the tweet embedded below.
