Art Of War mod is partial-conversion modification adding lots of new features to old Zero Hour's gameplay, they are discussed in summary.
Basically it is redesign of old Nuke Cannon, but it was also rearmed with usual high-explosive shells instead of nuke shells. It is available for all generals (including Tank General) after building the Propaganda Center.
At the third veterancy level Tactical artillery gains:
Tactical nuke shells (in case of Artillery and Nuke General)
Seismic shells (Infantry General)
Napalm Shells (Tank General)
wow, i was thinking of seismic weaponry too (for US)
U.S. should stick to their fuel-air and bunker busters. they are already powerful enough for big targets.
i mean i also thought of seismic weaponry, the difference is that you give it to infa gen and i give it to base america.
