I'm looking to build a human ex-ISB Agent, left for dead on Cholgana after his ship was destroyed and is now held captive by some crash survivors. I was hoping to make some good use of Ranged Heavy and my Cunning stat.

I was thinking about using the Skip Tracer as part of his build, but I can't seem to find much review on the spec. Has anyone used a skip tracer spec? What have you combined it with?

Skip Tracer would pair well with the Marshall from Far Horizons, or the Investigator from Endless Vigil. It also goes great with any Bounty Hunter specialization if you want to really play up the investigative part of Bounty Hunting. Also, any specialization with Street Smarts is good, because Improved Street Smarts could possibly be reduced to a Simple (-) Difficulty with enough ranks in Street Smarts talent.

I really like the Skip Tracer, but I haven't had the chance to play one yet, so I can't speak from experience. It's definitely not going to build on your combat skills much, but it will add some nice versatility. As for what to combine it with, in addition to the above recommendations, Scoundrel makes an interesting combination to really get more mileage out of Cunning and Presence by giving you Deception and Charm, the latter of which helps trigger Good Cop, and also provides ranks of Convincing Demeanor to combo with your Skulduggery and Bypass Security.

I'm also going to be the main ranged fighting guy in a group of an Engineer, Performer and Enforcer.

Marshal is not bad as its half shoot half social and had raps of good cop and bad
