a Modified landmine that you can atttach to other land mines via the k to a valid landmine/ chain detonator for when either of them detonate both of them detonate…
and perhaphs toggle them to be one way or both ways detonation… can see it now ,

Mines on outside will detonate on their own but the inside one will detonate all of them
The only problem with this idea is that it would only be useful against the Player, or tough Enemies. You wouldn’t want your entire minefield to blow up just because a dog wandered in or something.
When designed right it is more likely for the dog to just walk onto outlying mines and die on the ones that dont trigger all of them
though perhaphs also be able to make a weighted detonator, to where it goes off and only blows up enemys based on color of name
