Heroes of the Storm? The good news is that you can do so right now, even if you aren't currently in the test pool. The game's interactive battleground maps are now available, showing off the fields of battle and allowing you to zoom in or out, highlight important points, and scroll around to see all of the neat stuff that's there to be seen.
Each of the maps has numerous different mechanics as well as additional routes for players to take, including aboveground and underground routes or enemies that spawn during the night. The page outlines how all five maps will work and should help players start plotting strategies even without getting your hands on the game. If you feel like a bit of surveying, go check out the maps now.
