I've wondered at this as well. I watched a guy break into a base with a Sledge hammer, and though it seemed to take him forever. It couldn't have been more than a minute or so... I bought the game a month or so now, but learned a lot from YouTube vids. If they fixed the duck tape glitch, and tweaked (increased/decreased) the damaged received from the tool being used that could help. You can repair tools with tape right lol? As seen from vids though only way Is more walls, and gates... Make it a waste of time.
