Weapons

Ok all you have to do is when you're invadeing or defending or any battle you kill offesers and gens and you get hp. But it also and items to you're winning at the end of battle.. Rarely you will get an wepon or two but it wont tell you uv gotten it so you have to cheak alot to make shur. Some weps can only be onlocked in empire mode.. Same with items.

... Actually...

Use the Smith Policies during your Strategy phase. I suggest only using All Smith, unless you are only using one character throughout the whole game, then just increase his specific smith. At 100 smith points, you get your second weapons for EVERYONE in that smith. At 200, you get the third weapons for everyone in that smith. (You can see why I suggest All Smith.) At 400, you can go out an kill 500 enemies and you'll unlock your character's 4th weapon. This one only works for the character you're playing as. Also, weapons you gain in one Empire mode do not carry on to another Empire Mode, obviously. Good Luck!
