well in my opinion the only reason you would need the antigua is for its speed to break down the minerals xD seriously valiance and iron slug for a normal element gun or a piercing one would be better so that you would be ready for any and all ennemies. right now the antigua line is more for show than anything else. I'll have to complain a little, but compared to the sealed swords line, the antigua line is really useless, and it still has the same degree of rarity ! even a gunslinger fond of it will tell you that you can find a better gun easily, so don't raise your hopes too high and don't get it thinking it will be useful :) ( unlike me T-T )
