Our Strike was a self-contained affair, crafted to make a point: that Destiny really is a shooter in which you can have a blast shooting aliens with your friends, that the 30 seconds of fun gameplay loop that served Halo so well for so long is alive and kicking, and that in Destiny you can throw a grenade into a pack of enemies and watch bodies burn. Point proved. Destiny is a hell of a lot of fun.
But as the bullets are flying it's easy to forget Destiny is a "shared-world shooter". We'll be reminded of this later, perhaps while we're on a Patrol, collecting docking caps for some quest we just picked up from a beacon, darting around a huge map on our Sparrow one second, the next dismounting in the blink of an eye, shooting Fallen, opening a loot chest, summoning our Sparrow and mounting it in the same slick move, then speeding off into the distance.
