Ballista and towers.

The thing is, this isn't in WoG, but either in SoD or AB.

There is nothing like that in SoD. And even more so in AB. All of this is a feature of WoG and nothing more...

AmberSoler, sorry... But I've tried so many versions lately, I'm getting confused... SoD, WoG, Platinum, TE...

Only WoG and SoD are different.

Platinum is the same as SoD; it's just a collection that was given that name, like a "Platinum Collection of Heroes of Might and Magic." And TE is just SoD, refined for tournament battles (although everything is done on the WoG engine, there are no WoG-specific features there; they just tweaked the balance a bit and fixed some bugs).

So, if you can tell the difference between WoG and SoD, you won't have any problems... ;)
