Unless you happen to see one as it’s flying through the air (and survive long enough to see it land and destroy it), these buggers are ridiculously hard to find and destroy, and since finding and destroying it requires you to hide in its line of sight, you’ll be spotted and vulnerable to enemy fire the whole time as you duck helplessly trying to scan the surrounding area for a small dark node that is unrestrained by the confines of gravity and has no special visual indication of its whereabouts.
At the very least, they should have the same colored blinking indicator lights as Heartbeat Sensors (because shooting a friendly SNITCH is also annoying and a waste of ammo). Being able to stick it to walls and ceilings and high up places already makes them a challenge to spot, so its not like having them blink would make them useless or whatnot.
Anyone else think SNITCH devices should be made more visible?
