Destiny Walkthrough: Last Array Pt. 2 & Dark Beyond Pt. 1

Take down the last array then get ready to visit home of wizards, The Moon! Shoot your way though the waypoints and use cover when reloading. 

this area has some nasty enemies so dont stray too far from your mission objectives unless you are alittle higher level and things are normal for you and not hard. PVP is a great way to keep your level high and the story missions more fun than challenging.
