if you're worry bout no cheap tank dont cuz peeps only use crusader at early and not late games.
Once they get the money they can upgrade all the crusaders into CrusadersII which will be much more powerful (plez dont add the laser defense system, make it exclusive to Paladin)
Or if ya have time, ya could always get an upgrade for double barrelled paladin to be in the mod
BTW can you make a link to that website once you done with the mod?
