Raid is a game mode of Destiny. Raids are 6-player cooperative assassination missions that are of high challenge, and require communication between players to succeed. They involve specific quests for groups of fireteams. No waypoints or explicit objectives are provided. Raids typically involve epic, climactic encounters against various bosses, culminating in intense final battles against legendary bosses across the Destiny series. Raids differ from Strikes in a few ways: 6 player fireteams, as opposed to 3. No matchmaking. A player must form a fireteam beforehand or search on an LFG (Looking For Group) site.

In Destiny 2 the new Guided Games feature allowed solo-players to seek out Clan members to play within end-game activities such as raids. This feature was removed on November 3rd, 2020, coinciding with the launch of Beyond Light. Raid enemies will have abilities not found elsewhere in the game (i.e. unique enemies, debuffs, etc). Strikes last roughly ten to fifteen minutes, whereas raids can take up to several hours, usually only if players are new to the raid or during the initial few days following the release of a new Raid. Raids have no objective markers.

A player must find out where to go and what to do by themselves. Raids can be dropped and picked up at a later time in the week. Players don't have to finish them in one sitting, but they do have to finish it before their checkpoint expires every Tuesday, relative to your timezone (10AM PDT). Players will have the opportunity to acquire gear and weapons specific to a raid once an encounter is complete. The gear that drops from the raids will often have perks specific to that raid and are intended to make the raids easier if a player chooses to equip a piece of armor or a weapon from that specific raid, although they are not bound to that activity.
