Halo Reach ONI: Sword Base Walkthrough, How to Complete ONI: Sword Base Alone on Legendary
Part 1: The Best Defense…
This mission features a combination of both indoor and outdoor fighting, including many vehicular options in the outdoor section. This is also the first mission in which 38 super ammo for sale you fight Hunters, the most durable infantry of the covenant army. However, you are provided with multiple rocket launchers throughout the mission, making the Hunters relatively easy targets to kill.
You start this mission with a 50 ammo DMR and a 375 ammo assault rifle, in an area used as the “Courtyard” firefight map. Your initial objective is to protect Sword Base from a large group of covenant infantry in the courtyard. Directly in front of you below the bridge are four Grunts. As soon as your reticule appears on the screen, kill them with headshots, sprint to the bridge, and swap your assault rifle for one of their plasma pistols. Turn right into the hallway that leads up to the second story. In the courtyard, there are three Grunts, eight Jackals, an Elite minor, and an Elite major. At around this time, a phantom will drop an Elite minor and an Elite ultra with a concussion rifle as well. The Elite major is usually on the second story platform ahead of you when you enter the hallway, so be prepared to kill him with an overcharged plasma pistol and DMR headshot as you walk up the ramp in front of you.
After killing the Elite major if he was present, return to the hallway in order to take protection from phantom. Once the airspace is clear, move up to the second story once again and take cover behind the large UNSC Barricade. From here, pick off as many Grunts and Jackals as possible with your DMR. Periodically watch the ramp directly in front of you because Elites will often use this route to charge you. If they do, stun and kill them with your plasma pistol and DMR as they begin walking up the ramp. If you find yourself overwhelmed by enemies, you can also take cover in the hallway. This provides more solid cover than the large UNSC barricade but does not provide as good of a sniping position.
After you kill all visible enemies from your position, cross the bridge and walk to the left wall. Next to the corpse of a marine, you will find a DMR and a health kit, both of which you should use to restock. Move forward along the second story path ahead, and you will find a sniper rifle along the right railing. I would not suggest taking this weapon because it does not impart enough damage to kill most Elites with one headshot. At the very end of this path, there is a ramp heading into the courtyard, and from the bottom of this ramp you can easily finish off the rest of the enemies.
Keep walking strait and you will come to a maze of large UNSC barricades and large UNSC crates. Among this cover there are four Skirmisher majors and any infantry that retreated from the last fight. Select a barricade to use as cover and patiently kill the Skirmishers and any other remaining infantry. The Skirmishers often stay in cover, so you must wait until they walk between barricades or crates to achieve a headshot.
Move down the rest of the path to the covered area. Along the right wall, there are three weapons crates, one with two DMRs, one with two armor locks, and one with a target locator, as well as a health kit. Restock on DMR ammo and swap your plasma pistol for the target locator. As soon as you take the target locater, the doors will begin to open. Once you walk outside, you will move on to the next rally point.
