Defeating the Strider
After you climb the ladder and get up on the platform, you will notice a box containing rockets behind one of the metal sheets. If you get on it, you will be able to see a small part of the Strider but it will not see you. Observe its pattern of movement and fire a rocket just before it takes a new position. You will not miss by doing this. Keep firing at it until your cover breaks down. Until then you can easily score about five hits on it without losing any life. Then, move behind another metal sheet and finish off the Strider easily with one or two hits.
Easy "Conservationist" achievement
Kill five enemies with the same energy ball. They do not have to be killed with a single throw. Take an energy ball, throw it at some enemies, then recollect the same energy ball to throw it at more enemies. Although this can be done anywhere in the Citadel core, consider the "ep1_citadel_03" map, immediately after evading energy balls while crawling in a small tunnel. To find this location quickly, start a new game at Chapter 2 then enter the core and climb the first set of ladders.
Easy "Think Fast!" achievement
Play under the easy difficulty setting. When in the citadel near the start of the game, white elite combine soldiers will begin appearing. Quick save before a section where two or three of them appear. Kill all of the black armored combine soldiers. Stand slightly away from the elite soldiers and wait for them to fire an energy ball at you (listen carefully to know when this happens). Catch the energy ball that was shot and throw it back at the soldier.
