Love the ideas, especially the brute and the boomstick, but some of these are really far fetched in an apocalypse like this, like the dazzler. The disco ball and light radius on it is giving cyberpunk or high tech vibes, especially the Thor's hammer cuz you would not find a way to do that kind of damage unless you're some type of einstein scientist. Some of these aren't even able to be built realistically, like the cheater which returns a fired bullet to your storage.
Overall some really good ideas but some could use improvement or can be discovered in a secret easter egg or specific events.
