if you really want to agg the agents on you load out patcher or one of its sub branches then start healing your friends it never fails for me this even happens in places that ive tagged the node, but the npcs are higher level than me.it takes about 5-10 minutes of power healing to draw there attention,and then like another minute or so to get them spawned but then its on, those sob's wont stop untill im dead.
speaking of agents who here thinks the way they spawn is lame and inaccurate to the movies??
