This is the Amp i made from Infamous 2. I got the sling backpack with the hero edition so i thought it would be nice to have an Amp to go along with it. I made the Amp out of PVC and a few other materials I had around the house. The white blueprints were the final blueprints. They were close to perfect and had all the little details. The brown blueprints were rough blueprints i made very quickly to get my thoughts onto paper. The brown paper was not big enough so I split the drawings across three pieces of paper. The carabiners were there so I could suspend the Amp inside the sling pack.
