It looks nice and the rocket attack is cool as hell.. only 1 salvo though makes me a sad panda ..
But the artillery sound itself, not when striking home, but when its fired I was hoping for something along the lines of that distinctive, far off THUMP THUMP THUMP, the artillery in DH makes then the screaming noises as it arcs in to target
Other than that its great
Oh and is it me or is there any real difference between mortar or artillery aside from recharge time? As in most cases i go for mortars even on tanks as it seems to kill them as well easily enough
