And second, give the operative a tracking-dart ability that has a cooldown, which, when shot at an enemy makes them appear on the mini-map, and outlines them in red even when they are behind walls. This lasts until death, or when removed by a friendly operative.
The idea of tracking dart would be great! I understand it is similar to the homing beacon.
In which case I thought it would be nice to have a magnet dart. Such as all bullets will hit a marked target. Great for singling out that one operative disarming a charge - but I feel that it should take up all the Pips because the ability would be so powerful.
Most of the operative I have seen are also light/medium. Maybe dual wielding pistols?
