This is the first suggestion that i really like. I feel like a bear trap fits this game very well. Not only using to for maybe some added defense but even for what its made for, hunting. Being able to set a trap in the woods and coming back to find a prize waiting to be gutted would be very satisfying. On the other side having someone step into it and breaking a leg, possibly bleeding out would be equally as awesome to come back too. I also like the idea of requiring someone to get you out of it. BUT I can also understand why some wouldn't like it, trying to make your way through a town only to be stopped by a minefield someone took the time to formulate. Maybe just limiting the amount of traps a person can set? Also i don't think im quite sold on a claymore/bomb trap... not something id see fit for a zombie survival game. Personally i wouldn't be that upset getting trapped even if i was soloing around. Adds more the the thrill and insecurity this game offers.
