* Most boss-fight areas have sections of the terrain that are exploitable (enemies won't travel there and have difficulty shooting players hiding there, or can't at all). These are very useful for players attempting to solo Nightfall and Weekly Heroic Strikes. * If your Sparrow starts to roll or swerve out of control, let off the boost. Control comes back faster. * Completing a Nightfall Strike adds to your XP gain (+25% rounded down) for anything that gains XP - including Cryptarch rank, Vanguard/Faction rank, and weapon leveling. * You can cancel the last part of long reload animations by switching weapons, meleeing, or running. When you trigger the reload, look at the ammo indicator in the lower right. When the ammo refills there, use any of the three listed actions to cancel the remainder of the reload animation. Can be very useful with pistols and MGs.
