We should have a Destiny 2 season that revolves around stopping a giant Kaiju hive or taken enemy. The final mission could be you taking down the monster as it attacks the last city. The mission could be similar to a Monster Hunter World take boss fight. You have to set traps and shoot giant cannons and turrets to take down the monster. Meanwhile Ikora and other guardians are figuring how to super charge you with light to deal the final blow. (You could get a hive themed club exotic sword from the carcass of the dead titan covered in spikes). The rest of the season beforehand could have semi giant hive/taken that are surfacing around the Earth that you have to deal with and figure out where they are coming from. Savathun or whomever next, has figured how to birth larger and stronger hive unleashing their final and most powerful Kaiju for the final siege against the tower.
