Update #2 it out, and it's 2 new maps!!

An Arena map that plays unlike any of Valve’s Arena maps, with a heavy focus on vertical space and long, open sight lines. Control of the central building is a key decision that teams must wrestle over. More Sniper friendly than most Arena maps, it’s a perfect complement to the Scout update. Batter up!


A Gravel-Pit style map that the community has been heckling us to include for months. Junction is a sharp contrast to Watchtower. It’s full of tight spaces and short sight lines, which create combat opportunities dominated by ambushes and explosive weaponry.

I've never played these maps before, are they any good?
