It isn't really a FAQ, but a rules update for the Tetra, along with other Tau units. I can't find it on the website now, along with a lot of other rule downloads (which is weird) but it changed the Tetra greatly, and made them a viable choice again (in gaming terms). The largest change was the upgrading of the standard Marker Light to a High Intesity Markerlight.
