Assault on the Control Room (level)/Walkthrough

General Walkthrough
Now you completed the easy part of the game, we can now move on to the longest part of the game. In the beginning of the level, Foehammer will drop you off by the platform to the entrance of the control room, you will see Grunts running into the pressure doors to call upon their big brothers. Now you have two options. 1) Board the Shade Turret and gun everything down. 2) Wait for the door to reopen and chuck a grenade over the oncoming crowds. The first option is a little bit risky, because if you're playing on higher difficulties, the Grunts will always get on the turrets before you can even get close. The second option is an immediate tactic that saves a lot of time, although the Elites may survive the blast. Swap a Plasma Pistol for the Assault Rifle for your next encounter. Venture into the short passage, the next room is litter with Grunts, but before that, you will have to take out the Elite. Use a charge shot to disable the Elites shield and gun him down with a pistol headshot. Fairly easy, but the minor elite may have spotted you, and he will began throwing ridiculous amount of plasma grenades at you, lob a grenade at him to disperse the oncoming hoard of Grunts. Journey your way across the room, BUT DON'T get near the doors, because a hail of plasma by Jackals and Grunts will put you down. Lob another grenade (plasma or frag grenades, it doesn't really matter) at them, and proceed onto the bridge. The Bridge is one of the toughest parts in the level, with luck, you will loose one or two health bars; If you're one of the ones who always get unlucky in Halo, you might lose all your health. Melee the Grunts with ease, do it swiftly, because they will wake up later on (thanks to Foehammer's Pelican). Swap for the Needler over by the dead bodies. Again you now have two options. 1) Walk down the second level and blast the Major Elite or 2) continue your way across the bridge. The first tactic would be slow, but guarantee a safer route throughout your journey. The second tactic is quick, but will easily lead you into a situation where you find Grunts and Jackals surrounding you. All in all, you should succeed clearing your path with only pistol shots. Now I'll tell you what the Needler is for. Once you are at the end of the bridge, a Gold Elite with a Plasma Sword will come running at you. These are absolute monsters, with grunts on their tails. Back away and fire rapidly at the Elite, stop and you're a dead man. There is an easier way though, throw a grenade to soften up the crowd, and take on the Zealot. Anyway, after a lot of killing, walk into the next room. This room is fairly easy to complete, with a few Stealth Elites and Grunts, take them out with pistol shots and swap for the Assault Rifle and health pack lying on the floor. Take them down to the basement. Now at the basement, you will encounter some sleeping grunts, melee them with ease, and proceed. You will soon find an Elite wandering aimlessly back and forth, melee him in the back or just chuck a grenade at him casually, this will certainly wake everyone up, even if you did the job stealthy, because someone on the other side will probably see you. Gun everyone down nice and clean and proceed into the snowy grounds. The snowy playground is quite a nasty place with Shade Turrets, far ahead; you will see Fire Team Zulu fighting with Jackals and an Elite. The Elite will start running towards the Ghosts parked underneath a small cliff top with a shade turret on it. Use your pistol to gun down the Grunt by your side and the Grunt on the cliff top, and proceed to the Elites. Beware of the Wraith's fire though; they're dead accurate at overturning vehicles. After you put down the Elite, Swap for the Sniper Rifle or the Rocket launcher (Either one of them won't matter, you'll probably run out of ammo before you know it, you can swap the two weapons, which isn't recommended). And get onto the Warthog; drive it to the shady areas to pick up the Marines (in order to dodge the Wraith). Dash Forward, you don't need to wait for the gunner (if you have one) to put down the aliens. You will eventually run into a crashed Pelican and meet the only Scorpion that's parked with Marines. Board the Scorpion and proceed. Again you have two choices (1) Take the route on your left or 2) Kill the Ghosts on your right and proceed through the tunnel. Both routes lead to the next area, but the first option would lead you into a state where you will be surrounded by Ghosts and Elites. The second option however, would lead you into a confrontation with a Wraith Tank. Anyway, clear the area and you will see a way down to your next destination. You can choose to eliminate the Wraith tank on top of the hills, but careful, a Banshee will come and fire plasma at you. Just keep your head down and go into the tunnel. Drive your way through with confidence, you wouldn't encounter any Grunts or Elites on your way but once you reach the end and see two Elites (Major or Minor, it doesn't really matters...) stop right there, you wouldn't want to alarm them of your presence. Wait till they were just a step from each other, and fire a Scorpion shell to finish them off. Drive your way into the vicinity. Now be careful, because this is always where people lose their health and steps, and their marines. The bridge is littered with Jackals, two Shade turrets could be a small threat on lower difficulties, but you would want to take them out beforehand on Legendary. A funny way of preventing the Grunts on boarding the shade is simply blast the turret into the pit. Now for the Jackals. On lower difficulties, they're just aliens walking with toy guns, but on Heroic or Legendary, they're devastating beasts. Before you got onto the bridge, blast the first group of Jackals. Continue on and you'll see the next pack of them. These guys hold charge bolts and can take down your shield with ease, coupled by a few blast from the Hunter at the end of the bridge. Put them down, and stop at the rear end of the bridge.
