Format shamelessly stolen from the design document of the free indie RTS 0 A.D. Both for it's usefulness and as a chance to promote it.


I think Romans could use Siege Towers and train Attack Dogs from Farms.

Ancient Roman Battle tatic: Roman Archer formations used attack dogs to keep enemy shields down while shoting their heads, enemys would be wound be either ways protecting from missiles but being attacked by a dog, or shields down to protect against the dogs and being shot at the heads!

There's no point for Siege Towers for two reasons:
1) No walls. Wacraft has no wall system and I don't wanna mess with extremely complex triggers. So probably no walls either.
2) No suitable model. Unless someone is willing to add team colour to one I have in mind. But still, Siege Towers with no walls isn't that interesting to me.

First time I learn about this tactic. I might research on it a bit, but probably War Dogs will remain a Celtic-only unit. Romans have a good troop variety anyway while Celts are a little on the downside here. Plus I want factions to play a bit differently. Not on Warcraft levels, but not as similarly as in Age Of Empires either.

What if you add the ability for infantry to "assemble" into a catapult/siege weapon? (drew this idea from an old game called Nemesis of the Roman Empire)

You mean them pulling the weapon? Or garrison in it? If you mean the second, up to four infantry can garrison in Siege Rams.
