The Classic Battles mode is undocumented, and can be difficult to find.

It is only accessible from Battle List’s Host menu, via check box.

It provides a choice of 9 game-clans for you can play as, each with 26 units to choose from.

Each unit has 9 levels of upgrades immediately available, and additional advanced in-game features.

You can setup games of 1v1 to 4v4, with as many spectators as player spots not used.

There are 11 maps, and finances of 500 to 2250, and you can elect “not” to have key buildings if you wish.
