welcome to the clan, add me if you like my tag is same as my name here. its as pricey says you dont need expansion but if you love the game after a couple of weeks then get the expansion because the new stuff is great. as soon as you hit lvl 20 start doing the vanguard strikes to get the marks, then you can buy armour from the vanguard man which when lvl'd will get you to lvl 31, dont worry about weapons as they will com while your playing. armour first!!
