How about hacking them? Walk over to one of them with a wrench and you're switched to a mini-game reminiscent of Pipe Dream. If you can manage to direct a blue flow from point A to point B, the mine only kills your enemies
!
Or would that be too BioShock-ish?
On-topic, it still strikes me how strange it is that mines incur so many team kills. Don't go near the red x. Don't punish if you do. How hard is that to get?
