Better yet, don't build most of your traps. A level 1 trap adds 30 to the base score, which is more than a level 1 turret. If you don't build them, you will get to loot at a higher rate (30% on alloy/credit vs the normal 20%, and ~18% on cb vs the normal 10%). My level 8 has 4 maxed out traps; I wish I only had maybe 2. At level 10, there are just too many traps imo. We never had the striker traps on windows, but it got to be a major pita to place all of the other traps. You're almost forced to design you base around the stupid traps, which makes no sense. And you also spend a ton in alloy fixing them if you leave them out in the open. I really, really doubt that you save loot by building traps. In the long run, you'll save (or loot) much more alloy without them.
