Weapon loadout thing is long gone, now every weapon you have unlocked seems to be available in one big menu.

I can see their niche now though. They’re emergency crowd control.[/QUOTE]
They are on different cool downs, was mentioned by a dev in an interview somewhere.
I actually think it works that way. I remember reading about it, what i remember though is it saying the mission led him to the area where the mines were. So maybe that is just a general location and you have to find them yourself once you are in the area? Then again, my memory might be playing tricks on me too.
Then, as Biosnark noted, maybe it was too powerful and needed a counter, so they are invisible but you can’t expect them to be visible for very long because they lead the covie by the nose to them.
Spotting always makes for some interesting tactics, if the are spotted and aren’t in a chokepoint, you just leave them there. Enemy engy isn’t aware he has one less effective mine on the map. If you instead diffuse it he will just re-plant it again, this time hidden. …of course, engies probably get a lot of XP for disarming them so only organized teams will end up leaving them alone.
And when they are spotted i think they have the bif red outline for everyone on your team? So leaving them really is a viable option since in that case they would stand out like a stoplight.
