Defeating Promethean Knights​

When there are multiple Promethean Knights in an area they can be very troublesome (especially under the Legendary difficulty). To easily dispose of the knights, make sure you have a mid range weapon (pistol, DMR, battle rifle, carbine, light rifle, etc...) and the shotgun (or equivalent). Start by using your mid range weapon to head shot one of the knights from a distance, but use a low rate of fire to conserve ammo. Fire only one shot every couple of seconds. This will tick off the knight and "bait" him into doing the teleporting-dash across the map to melee you, thus bringing him in close and separating him from the rest of the knights. When you see the knight begin to teleport-dash towards you, quickly run backwards and slightly to the side to dodge his melee attack, then switch to your shotgun and blast him at point blank range. Repeat this tactic as necessary.

Easy "Skullduggary" achievement​

Play through any campaign mission under Legendary with the IWHBYD, Grunt Birthday party, and Cowbell Skulls enabled. These three skulls do not increase the game's difficulty by too much, and count towards the achievement.

Navigating the Broadsword during the last mission​

During the part where you are flying the Broadsword ship through crevices on the Didact's ship, whenever you reach an area with an open ceiling you can fly over most of the obstacles and turrets, making it easier to traverse the beginning of the mission.
