Here is what the main ‘play battle’ screen looks like for GTB. The current plan is for three basic modes of play. The campaign scenarios, custom maps, and online maps, as shown by the three tabs at the top left of the screen.
The big map image changes to be a list of maps in the other two modes. The right hand pane shows information about the current selected map. Custom maps are ones you edited or designed yourself and saved locally. The online ones are maps you, or other players uploaded to be played by everyone else.
I still need to add in display of some high score data on that gap on the right. Also, a few of those buttons are debug-only, but you will have the option to play any map as attacker or defender, and to edit it and save it however you like.
I love company of heroes, but the map editor for it is ferociously complex, and there is no easy way to trivially change a map, then give it to a friend to play. My aim is for that sort of thing to be trivial in GTB. So when a player thinks that tile 16,24 should be place-able by the defender in map #4, he/she can just click edit, change that tile, then save it as a custom map for himself, or upload it as an ‘improved’ map #4.
That’s the theory.
