Thanks for posting about the game Echoseven
Just wanted to add that the main new feature we've added to this game in our Civil War series is the map zoom feature. It let's you use the pinch gesture to zoom in and out of the battle to get a better overview of the battle and includes a simplified (symbolic) version of the terrain.
Also it's possible to control the units from the zoomed out view
Finally, we're planning to update all our other hex strategy games with this feature and also utilise it further in future games to allow even larger battles!
