Internal Testing for the .993 public beta has started. So far we've been testing CamosCrossing, Fissure, Volcano, Metro, and Canyon River. They are all excellent maps, and extremely fun to play. The weather on Canyon River works just as planned too(starts to storm 15 minutes into the game).
Go here to see all the images we've taken so far. And Ignore any bugs or errors you see as of now, since the purpose of these tests is to find them.
