Brothers Steven and Robert McCann were the founders of McCann Weapons Systems, an advanced weapons developement company. After presenting several of their ideas to the government of The Republic of Ireland, they were shut down by their government. The Republic of Ireland felt they had no use or need for such advanced weaponary.

Steven and Robert continued their research and development in secrecy. After being discovered by government officials, Steven and Robert were arrested and their weaponary and research work confiscated.

Several McCann family members gathered and plotted. Steven and Robert were sprung from prison. The McCann Weapons Systems was back in the hands of the McCann family.

And thus begins the saga of the McCann Clan.

The McCann Clan is currently working for Death's Rangers.
