Well I hate to break it to ya, but the weapons in the "Arsenal Pack" are crap - 15 minutes on the first story mission and you'll likely drop better weapons anyway. You get them at the Quartermaster in the hanger - they're green, with 160 damage and it'll cost you 1500 glimmer for each one(!). The emblem and shader kinda made up for it (not really) but now they're gone. Coulda spent that $40 on Forza 6 or waited on Fallout 4...
