In Star Trek Elite Force 2 For Mac Part 18 Payback Part 1, You are looking for Krindo.
He has unleashed the exomorphs onto an attrexian colony and killed many of them after attacking the Enterprise. Your shuttle has crash landed on the planet they are coming from. Go out and find Krindo, stop the exomorph reinforcements, and help your shuttle crew. I was able to find all of the golden starships too!
