Destiny Signature Series Strategy Guide Expansion I: The Dark Below Crucible Maps
Skyshock

Skyshock is arguably the biggest map in PvP. It has wide open plains, close quarters building combat, and some planes rusting away near the edge of the map, making this map a tactical nightmare if you lack a team.
At the start of the match decide if you want to rush and attempt to flank the enemy, or focus on getting a tactical advantage for the middle objective fight. The middle objective is located far to the side of the map, opposite the downed planes, drawing most of the combat to the center buildings. With all the fight happening near the objectives, try weaving through the planes to conceal your movement while working towards the enemies' flank.
There are three heavy ammo spawns on this map, all of them next to the 3 control objectives, if the enemies are taking an objective, grab ammo and rush in. Taking the ammo will not only increase your odds of clearing the objective, but it will also take the majority of it away from the enemies that are capturing the objectives. Experienced players will benefit from using a Scout Rifle for the outdoor areas and a shotgun or fusion rifle for indoors. Newer players may wants to use a Sniper Rifle to get one shot kills from a distance, then use an Auto Rifle when moving into close quarters areas.
