First things first get the gun you want inf ammo for, then save your money, then upgrade the weapon to max. max out everything then go to bonus features and find it where you buy your figurines then buy it. then go to special settings and you should see infinite ammo if not beat the game first i beat the first before i know about this.

I dint know this nice tho lets tried but thanks for info oo you are new here welcome
