Absolutely. i use one of each in my lists (1khd, 1 combi/Riotstopper). It's a good midfield camo hunter in a game where lots of midfield camo has shotguns or SMG's. It also has enough 'ugh' that units stay away from it where possible.
After the last games I have to say that the Delta KH has a lot of potential too. He can't be attacked (if he is not on the board) and can start even further in enemy territory.
also packs D-charges for the Sabotage card! Combined with being "Veteran" troop type and MI, this guy can complete like 2/3rds classified cards
I have played a lot of NCA and the Hexa KHD is one of my favorite profiles. It is beyond good, KHD for when you need it, an extremely good backup gunfighter because of TO, marker state to get around and prevent enemy KHD from zapping you, specialist to push buttons. I usually activate the Hexa turn 2 or 3 either to do the objective or to finish killing people. Now the new Lynx is like a Hexa, but better. For 1 more point than the Hexa you get: BS13, Wip14, 3 BTS, cyber mines, and a breaker combi. An insanely good package. Gives your HI KHD protection and then you move around killing everyone while also pushing buttons. My Hexa KHD has probably killed just as much as my Swiss HMG.
