If They Came to Hear Me Beg

If They Came to Hear Me Beg is a Campaign Achievement in Halo: Reach. The achievement is awarded when a player performs an assassination against a Sangheili to "survive a fall that would’ve been fatal." It is represented by a combat knife over red, circular saw blade.

Methods

 * The easiest way to get this achievement is at the very beginning of The Pillar of Autumn. At the bottom of the cliff, there is an Elite and by jumping off the cliff using sprint, it is possible to get the achievement. Remember to deactivate sprint just after jumping off.
 * It is also possible, albeit very difficult, to get the achievement while jumping off of the spire on the level Tip of the Spear.
 * There is also a ledge in the beginning of Nightfall that makes this possible, albeit difficult and rather unlikely. Should probably be attempted only on Legendary, and note that this ledge is above the pathway the player and Jun take, requiring one to take it, and double back on top.
 * Apparently the coding for the achievement detects when or if the player touches the ground when landing to perform the assasination even if it didn't cause him/her to die, so an easy way to fix this is to crouch while on the air to not to it, however it makes more likely to perform a Beat Down rather than an Assasination.

Trivia

 * The achievement's name is derived from a quote by Thel 'Vadam during his shaming; "If they came to hear me beg, they will be disappointed."
 * This is regarded by much of the community as one of the hardest and most annoying achievements in the game, due to the tendencies of the AI Elites to randomly move as the player is falling.
