: From personal experience, in Ingue Ferroque , in both the current beta and
: original, playing on Total Carnage, a single invisibility power-up is
: sufficient to avoid detection until you are (approximately) within 3-4X
: punching distance, which is to say you can be detected, but you have to
: get almost right on top of the Pfhor to trigger them. This is enough cover
: to skate past most of the fight in the first ring, and then in the second
: ring, have just enough time on your cloak to run up to the waiting
: projectile troopers, have them become just visible in the dark from the
: shine of your player "glow", and grenade or rocket them while
: they are napping. This works just fine in the beta, and I have done it in
: the original Marathon more times than I could possibly count. :)
Heh. I don't think Bungie ever expected the Transparency BCE to be used for this purpose. But it's a good one.
They were clearly designed to help you take out the Jugs. Hence their locations.
