Claymores are not yet a thing, to my knowledge. It’s been discussed before. Last time I asked questions about cones . . .
That’s from Booby Traps & Area Denial: Claymores, Bouncing Betty, Spring-gun, Deadfall Traps, Electrified Floor, Motorised Blades, etc - #6 by TheMurderUnicorn which was back in December. I don’t think cones have been implemented since then, though I haven’t been keeping up with the state of things like I used to.
