Imagination is the only limit. There could be plenty of neat and new mechanics. For instance, the raid could involve freeing the Queen from a group of Fallen who have betrayed her. You and your fireteam have to break into the Queen's fortress in the reef by avoiding Walker Tanks and deactivating her security defenses with the help of her brother, Crow. Once you reach her chambers, you find the Fallen have taken her aboard one of their large ships in an attempt to escape with the Queen. You and your team must then hijack it just before it takes off (timed fight to board the ship before it leaves). Once in space, your team must fight through the ship while gravity is turned off and or changes at various times as the vessel takes damage from your assault. The ship eventually is disabled by your team and eventually crashes on an unknown, rocky planet outside of our solar system. The Fallen try to recollect themselves and take possession of the Queen, but find that their ship has crashed in the middle of an ancient Ahamkara nesting ground/lair. You confront the Fallen leader and his guards amongst the wreckage of his ship for the final fight. The fight involves various phases in which players will see Ahamkara younglings interrupt and attack both parties. Guardians will need to manage both their safety and the Queen's as they fight off both the Fallen and Ahamkara. Half way through the fight, an Alpha Ahamkara bursts from the planet's brittle surface and attacks both sides, much like the younglings. You will need to work the fight so that the Fallen leader and Alpha Ahamkara damage each other by leading their attacks/aggression...all while making sure the Queen stays safe. Once both are heavily damaged and one kills the other, you must then focus your attacks on the weakened one. If the Fallen leader is left alive, you will need to use different tactics and vice versa for the Alpha Ahamkara (i.e. different damage types, abilities, etc.). Eventually the Fallen leader/Ahamkara is slain and the Guardians succeed in saving the Queen and activate a distress beacon. Crow shows up moments later in a Fallen ship and thanks you for saving his sister. You and your team realize that there is no way he could be responding to the distress beacon as he arrived too quickly. You confront Crow as he tries to take back his sister and he attempts to kill you and your team. This is the true final fight as your team battles Crow and his ship, which hovers above and attacks with concussive shots as well as releasing teams of Fallen who disable a random player (your team must kill the group of Fallen in order to release the player). During the fight you learn that Crow was actually trying to dethrone his sister and agreed to give the House of Wolves more power if they helped him. It turns out, he was trying to sabotage your rescue attempts earlier in the raid. The fight is ended when Crow is killed by getting him to a ledge and knocking him off a cliff with a well timed concussive blast by his ship, which takes timing and careful positioning of Crow, who fights using quick agility, melee, grenades, and dual handcannons. If players fail to knock Crow off a ledge within 10 minutes, he enrages and activates a similar Blade Dance ability while his ship begins to do constant bombing runs.
