Without a lot of details, this is an easy way to get a advantage by having an extra upgrade to your weapon. Downside, your second weapon has no upgrade. Equipt the weapons you want and add upgrades, the upgrade on second gun can be overwrote with the 2nd upgrade you what on first gun. I am including my save with all 4 classes with main weapon has 2 upgrades. If you are interested in more details just ask. http://www.mediafire...s0gxw8wjpgupoic just click on content and replace with this. When you load the save it might say something about missing dlc just follow prompts and you will still get the upgraded weapons but you might not get the dlc chassis, Enjoy. Questions and comments are welcome and well be answered promptly.
