Well im not sure if bomb / mine actually matters, ive been using the IED or explosive charge and setting it with a trigger for a much larger explosion, as to bring buildings down. That idea of leaving something nearby and destroyable is a good diea, i could even do it with the buildings that would of been destroyed. Only issue then being, how do i tell the mission that all the bombs where disarmed so mission end? Possible to have a trigger that cuases end when they are all !alive but then checks to see how many buildings are left and then give correct ending? a lose for all destroyed a minor win for 2 - 3 still standing and a full victory for them all standing. Is that possible or am i just getting too far ahead of myself now?
