Nevermind the barrel, tell me more about the Chicken-Cactus trap on the right!
Seriously, if we get petards then perhaps they could take the shape/texture of barrels. It would make sense to have more than one way of detonating them (timer, blunt impact or shot from afar like in Jaws), then it’s up to you if you want to take the “hit”, so to speak.
Yeah 'cause landmines are so fun…
Bear traps are in game because they are outdated and illegal in many places, hence fair game in pop culture. Landmines are still blowing the limbs off of small kids in some places round the world, so the relative shitstorm created by their inclusion into Rust just wouldn’t be worth it.
Some tripwire as a trigger for stuff would be good, but this would just be annoying. Landmining someone else’s door while they go out and collecting all their resources when they return means: game=broken.
