Into the Belly of the Beast Walkthrough After a tense moment, the Covenant will start streaming into the room. The first one you'll meet is a cloaked Elite, who is carrying a laser sword. If he hits you with it, you will die. So will anybody on your crew, so you want to drop this stooge as soon as possible. Track his laser sword and try to line up a head shot with the Sniper Rifle. The quicker you can make this guy fall, the better. After he's gone, the floodgates open and a bunch of Jackals, Grunts and Elite pour into the room. What follows is an extended battle in this large room. Use grenades whenever a door opens to kill groups of enemies quickly. Keep track of where your enemies are on the radar (they come from all sides) and use the large canisters scattered around the room for cover. Behind one of them, you'll find Active Camouflage, which will cloak you just as the Elite was cloaked. Use this to sneak up on Jackals and Grunts and hit them with your melee attack, which will save you both time and ammo. There is also a health pack in the same corner, if you get too chewed up. Once the fight has ended, collect up the remainder of your troops and head through the only open hallway leading out of the room. You'll come to the end of a blocked- off hallway. You'll have to find a way to get around it, so return to the room you beamed into and go through either door with a white border. No matter which path you choose, take a right when you reach the wall, mowing down the Grunts and Elite you encounter in this passage. Follow the rightmost path all the way to a circular room with a column at its center. To the right of this room is a door. Tease it open, then chuck a grenade into the room in the direction of the Jackal and Elite on the left wall. There is an Elite further down the path as well. Drop this line of enemies, then move into the room. You'll find yourself in a huge bay. When you move forward, Cortana will tell you that she found the door she was looking for. It is indicated as a nav point in the room below. The marines will work on opening it. If you want to save yourself some trouble later, kill all of the enemies in the room below before proceeding. The Sniper Rifle works dandy for this task. Then move through the doors on the far side of the room. Battle your way through the Grunts in these corridors, following the path down. A good rule of thumb is to follow the trail of enemies. They'll lead you to your next destination. Near the bottom of the path, you'll run into another Elite. Kill him with the Sniper Rifle, then move through the yellowish doors here. The hallway will dump into the room you were looking at from the walkway above. Wipe out whatever is left of the enemy here, then brace yourself for a new batch. A couple of Elite will come through the far door, followed by a slew of Jackals and Grunts. Hold your position near the doorway you entered through, and attack these guys at distance with the Sniper Rifle. Note: There is a health pack near the doorway, but hold off grabbing it until your life is running low. When all the enemies in this area die, move to the nav point to find a glowing control panel. Press X to open the muster bay door. This will reunite you with your marines. Once they arrive, move through the white rimmed doors to the right of the muster bay (when facing the controls). The path will lead down. Follow it to the left to find more foes: Jackals. As you continue down the path, you'll reach a long hall with Grunts and Elite in it. Toss a grenade to clear soem out, then finish up with the Assault Rifle. As you clear enemies, move down the path. You'll notice several red-lit hallways to the left. Ignore them and forge ahead, making bodies hit the floor the whole way. You'll hit a checkpoint just before the path dumps into another huge bay. Your marines will join you for a huge firefight. There are Grunts and Elite galore in the battle, courtesy of a Covenant dropship. Watch out for enemies on the platform ahead and above. There is an especially nasty Elite that will eat your soldiers alive unless you drop him with the Sniper Rifle. Stay near the doorway you came through and take your time smoking the baddies here. After you get past the first wave, more Covenant will appear on the platform above and through doors to the right. The Jackals on the walkway above should be taken down with the Sniper Rifle before focusing on the ground troops. After the second wave is dead, a checkpoint will occur. Move into the room. Straight ahead from the door you came in through is a health pack and ammo stash. Grab it, then move to the other side of the room. When you do, more Covenant will stream through a door in the other half of the room. Look at your radar to see where they're coming from, then move to that doorway and fill it with grenades. A couple of Elite and Jackals will emerge from here, and the more work you can do with grenades, the better. When this wave is wiped out, you'll have an even nastier group to contend with. Fortunately, before they arrive, you get a new dropship full of marines as well. To trigger them, head back to the other side of the room. Near a couple of canisters you'll find and Overshield. Grab it to boost your protection. Then turn and face the oncoming rush. Focus on the Elite. Your marines will do a good job with the smaller stuff, but you can help them a lot with some well placed Plasma Grenade throws. At the end of the battle, two Hunters will show up. Use your Sniper Rifle on their orange parts for a couple of quick kills. Be sure you dodge their green energy blasts, though. When all the enemies die, Cortana will open a door in the bay, marked by a nav point. Move through it and battle down the corridors with the help of your Marines. As the hallway begins to slope up, you'll run into a couple of cloaked Elite. Use your Sniper Rifle on them. If you can get a head shot, all the better. Keep moving forward... your marines will point the way. Eventually, you'll exit into another large bay. There are several Grunts guarding the left walkway. Plow through them and enter the white-rimmed door. With your marines, battle through the winding corridors. You'll encounter a few Elite on your trip. Save your grenades for them. There is only one way to go through this passage, and it leads to another open bay area. Here, you'll encounter another Elite and some Grunts. Drop them, then move around the central opening to a door on the far side of the room. Follow the path up until you reach a crossroads. Down the left leg of the crossroads, you'll find a stash containing a health pack and a buttload of ammo. Grab it, go back to the main path, then move ahead. At the top of the path is a door. Hang out near the doorway and switch to the Sniper Rifle. There is an Elite carrying a laser sword atop the central platform. Drop him, then focus on the other Elite that start to rush. When they all die, it's time to move to the nav point. Kill the Grunts that approach, then follow the winding, purple paths as they lead up to a seemingly empty room. Move to the end of this room, where you'll find a glowing control panel. Activate it to open the prison doors. Then head back out of the room and go straight, following the path until you see another enemy appear on the radar. It's a Jackal. Take it down and move down the hall until you reach a passage that breaks off to the right. There is a killer Elite with a laser sword on patrol at the end of the room. Take it down with the Sniper Rifle, then find the cloaked Elite also in this room and take it down. Several Grunts will swarm into the room at this point. Slay them, then move to the other end of the room and open this set of prison doors.
