Rescue Captain Keyes from the Covenant Cruiser Eliminate the Covenant Troops in the first area without being discovered Foot-units get priority over the ones on the mounted guns, but bear in mind that if you are detected or you stray too far from the right side the Marines that are with you will attack, and if that happens you cannot unlock this Achievement. To accomplish this what you need to do is stick to the cliff wall on the right of the first area and snipe your targets without giving away your position. All According to Plan (10 GS) Kill all of the enemies in the first encounter of 'Truth and Reconciliation' without being detected. That may sound easier than it actually is - but one way to make sure that you do end up unlocking this is to replay the level with your second gamepad active and use that character to do most of the sniping, which pretty much guarantees you unlock this one. Close Quarters Combat (25 GS) Complete the level 'Truth and Reconciliation' with at least four rounds left in your Sniper Rifle. Level Notes: Truth and Reconciliation has three Achievements directly associated with it - the standard Achievement for completing the level regardless of difficulty level selected, and a pair of optional Achievements that are based upon specific actions/results and not difficulty. (4) Hunters - Very accurate shooters / Kill On Sight (Groups of Two) (3) Elites - Both types are present, the Red seem more dangerous as they melee (2) Jackals - Try not to let them get close enough to melee you (1) Grunts - A mixture of both types / dangerous in packs
