Battleship, Hangar Bay
Hale goes it alone on board the ship, taking the central path exiting the hangar while the rest of Echo Team goes left. Walk forward through the hallway, then hang a right at the second junction. Go left at the next intersection and shoot down the charging Chameleon. Proceed forward to the duct, but before crouching into it kill all the leapers that crawling inside. A few more will roll at you once you're inside, so keep your aim steady. Upon exiting the duct, pick up the Fareye to make short work of the hybrids up ahead. Only one way to go, so move forward until reach an elevator that takes you down a couple levels.

Go right when you exit the elevator and destroy any of the drones that hang back. Pull out the Fareye and snipe the hybrids at the far end of the room. Be mindful of the Ravager accompanying them, as he can quickly whittle away your health. Also, you only have so much ammo for the rifle, so don't waste bullets and take your shots carefully. When the coast is clear or you run out of bullets, move up.

Battleship, East Corridor
You should come to an area featuring a small room to your right filled with spinners and a Marksman on the ground. Another good opportunity to rack up spinner kills for the trophy-minded. Do kill the two hybrids that assault you before doing so, though; additionally, swap out your Fareye for the Marksman when that's done. Resume sniping at the hybrids ahead before continuing forward. The fewer enemies in the section ahead, the higher your chances of survival. You can take out the hybrids below your position by crouching and then shooting from the very edge of the bridge. There's a short area without a protective rail that you can use to get a vantage point. Don't concern yourself with killing them all, since they continuous stream out. Just get enough of them so they aren't damaging you too much.

Move forward after switching to the Bullseye. Kill the hybrid in the hallway with it and prepare to take on two Auger-equipped enemies shortly thereafter. Make sure you rest up before fighting them, not walking forward until the screen is clear of red edges. When engaging them, focus on one at a time. If you have any grenades, chuck them to soften them up. When you fell the two, pick up their Augers in replace of your Marksman and continue forward.

After picking up the Auger, hold it and switch to your Bullseye in anticipation of a Chameleon in the hallway ahead. He charges from the center, which makes the shot simple. Continue and take a right at the second intersection. Sometimes a Chameleon will charge from the far side of this section of the hallway, but not always. Stay alert. Hang a left immediately after the last turn, being careful to shoot the Chameleon that runs at you. Hang a right after the last Chameleon encounter and crouch to go into the vent. No leapers in the first part, but there are a few that appear once you've dropped down while inside the vent.

Battleship, Bridge
There's another drop after that which takes you near the bridge and smack in front of an Auger-equipped Chimera. Load him full of Bullseye fire and melee to kill him. Circumvent the wall to the right of the control panels and reload in preparation of a wave of hybrids on the other side of the wall. Grab the hedgehog grenade just a couple steps from the wall on the opposite side and throw it rid yourself of a few enemies. Clear the remaining forces out using your Auger. With this initial group dead, another pair of Auger-equipped enemies and a hybrid descend from the elevator ahead. As long as you have some bullets left in your Auger, they're easily eliminated. Use your Bullseye effectively if not. Go up the elevator when they're gone to set the charges on the bridge.

Battleship, West Corridor
Head in the direction you face at the end of the cutscene. A pair of Chameleons will rush you, which are easy to kill with a couple shots from your Bullseye. When you reach the second ramp, another Chameleon charges you. You should not be in a room with three possible routes--one to the left, another in the center on the opposite side of where you enter, and the third to your right. Reload your gun and kill the Chameleon in the path to the right, which takes you to a lift. Use it to continue your evacuation of the ship within the allotted two minutes.

Don't freak out about the time limit, as it's more than enough time to make your escape. When the lift hits the top, go down the only viable path avoiding fires along the way. After a few seconds, you should reach a group of hybrids and an elite. No need to fire on them, as a scripted explosion will kill them for you. Continue forward to meet up with Echo Team using the waypoint as a guide. Depending on how much time it takes you to reach the scripted enemy explosion, you may have a clear path to the escape shuttle. If you have a significant amount of time remaining, you'll be forced to defend against an onslaught of hybrids until the hangar door opens. Take cover and only pop out to kill hybrids advancing on your position. You just need to survive long enough until the clock ticks down and the door opens. When it does, run in to finish the mission.

Mission 3: Twin Falls
While Echo Team succeeds in blowing up the Chimera battleship, it's a bumpy escape. Warner is unable to stabilize the shuttle after the explosion and the team crashes in the middle of Twin Falls, Idaho.

115 Warrington Drive
From the crash site, head into the basement of the house in front of you. The game prompts you to flick on your flashlight, although you can get through the flooded basement without doing so. Go through the first room, turn right, then walk to the stairs slightly to the left of the door frame. Once up the stairs, you should be in the kitchen. Continue moving through the house, walking through the bedroom, then family room, and finally living room to reach the front door. Exit and scout out a route to the waypoint that now appears. [INTEL #13: Leaning against the car outside is a case with documents.]

Start by going through the garage to reach the backyard of the neighboring house. Enter the house from the back door (after sending nice thoughts to the doggy that's been spun up in his house). From the kitchen walk forward through the door on the opposite side of the room from where you came in. A staircase to you right is where you need to go. Head up and venture into the bedroom on the left side of the house where the residing couple lay to pick up a Magnum. Go outside to the deck and take a gander at all the spinners. Take some out to continue your "Snipe Hunt" trophy quest. Drop down to ground level and pull out your shotgun to blast Grims that burst from the cocoons. Navigate through the yard to get to the opening in the wall near the waypoint. Hawthorne meets you there.

After a brief conversation, a new waypoint pops up behind you. Getting to it means going through the house on the other side of the street. Enter the living room, then take a left into the family room and blast the Grim that emerges there. Continue through the house. At the back door is a Carbine--skip it for now and hold onto your Rossmore and Magnum. Now that you're in the backyard, run toward the waypoint. A garage to your right houses a couple of frag grenades and ammo. Stock up and continue to Warner.

Getting inside the house involves dropping down into the flooded basement. Shoot the three Grims that appear and find the stairs to the first floor. They're in the same spot here as they were in the other house's basement at the start of the mission. Clear the first floor and meet up with Warner near the stairs. Head upstairs and prime your shotgun for several Grims that emerge from the bedrooms. [INTEL #12: In the area between the kitchen and living you ought to find this document. Just make sure to search the house thoroughly before you leave.] Jump off the balcony to return to the backyard.

The objective is to return to the barricade where you first spoke with Hawthorne. A ton of Grims impede your return, so utilize the shotgun to kill multiple Grims with a single shot. When you've run out of ammo, switch to the Magnum. Make certain to leverage the explosive power of its secondary fire. When you run out of that, pick up the Carbine you left at the back door of the house near the barricade and use it. Lastly, the two grenades you picked up from the garage can be very helpful if thrown well. Wait for a large cluster of Grims before chucking one. As soon as you get back to the barricade, run up the fire escape and drop down to the other side. Scurry up the tilted train car to continue down the street. Before walking down the alley, blow up some cars if you want to get the "Wrecking Machine" trophy. If you got enough during Orick, you can unlock it here.

Main Street
Snatch the Marksman at the end of the alley in place of your Magnum. Hang back by the barbed wire and use the Marksman to take out hybrids from a distance. This makes it much easier when you move up to Warner's position. With the area around the gas station clear, you can move up to the diner where you need to take out four Augers. If you have any ammo left in your Marksman, use it to snipe them through the windows. There's additional Marksman ammo at the other side of the gas station between it and the diner. Another option is to run to the front of the diner where you can pick up a Bellock and lob grenades through the windows. [INTEL #11: Before going into the diner, search the charred vehicles in front of it to get this document.] Take an Auger once inside the diner. It comes in very handy in the tight spaces ahead.

Make your way to the back of the diner and follow your buddies up the ramp on the left. Stick with your squadmates as you enter a grocery store. Pull out the Auger and bear down on Chimera forces taking cover behind the shelves. Kill the Augers first before aiming at the hybrids. Run along the wall in which you entered to identify targets in green with the Auger and then fall back once you're got them in your sights. Don't leave the room before picking up the pair of hedgehog grenades on the counter near the door.

Exit the store and walk through the alley to reach the beauty salon. There's a barn on the other side of the salon packed with hybrids and a pair of Augers. You can either chuck a hedgehog and quickly back out or simply head in, identify the targets for your Auger and then back out to shoot them through the walls. A combination of both tactics works well. Watch out for a trio of hybrids that run out after you clear this initial group. Exit the barn and grab the spider grenade and shotgun before going into the theater. Throw it toward the seats as soon as you go in, then start pounding away with the Rossmore. Return to where you picked up the shotgun once the theater is clear to swap out the weapon you dropped. Now go into the lobby and finish clearing the building out.

When you come out of the theater, you're greeted by a Titan in the town square! Three, in fact. If you still have an Auger, fantastic. Equip it and identify the closest Titan. Crouch in front of the first car outside the theater and unload on the targeted Titan until he goes down. Taking the remaining two out can be difficult if you can't reach the Bellock grenade launch to the right of the gazebo in the center of the square. Keep moving to avoid their fire and unload bullets whenever you get an opportunity. Grenades can be picked up at the far corners of the square opposite the theater--a few frag and some hedgehogs. Also, steer clear of a Titan when it's about to explode since it will damage you. Dying right after you just felled all three would be enough to make you want to chuck the controller.

Stock up on ammo before meeting up with the team at the waypoint. Go over the telephone booth to the other side of the street and engage the enemies there. With the alley cleared, move up into the train yard.

Train Yard
On the tracks, navigate through the rail cars to reach the tunnel on the right. At the first support pillar in the tunnel are a pair of frag grenades and Carbine ammo. Definitely pick up the grenades and ammo, if you need it. Move up and kill the dozen or so Grims that pop out of the cocoons. A Rossmore along the right side of the tunnel next to a broken car may help take some out. Follow Capelli through the tunnel. Don't try to preemptively kill Grims by shooting the cocoons because it just wastes ammo. The Grims will still appear because there are so many of them, so it's better to wait for them to emerge and time shotgun blasts to kill several at once. Additionally, staying close to Capelli enables him to take care of a few.

Walk from the right side of the tunnel to the opposite side after Capelli's lead. Kill another set of Grims, then stock up on Rossmore ammo. Move up, kill the Grims that drop down from the ceiling and then collect the grenades at the crates ahead of where those Grims dropped. Continue forward and defeat another batch of Grims before reaching a ramp that takes you out of the tunnel.

After the leapers make for a hasty retreat, drop down from the ramp and move forward on the bridge between the two railway tunnels. Stick to cover in order to avoid Ravager and hybrid weapons fire. Two Ravagers and a hybrid will quickly come at you, which you can take care of by throwing a frag. Afterwards, pick up the Marksman to the left side of the bridge and snipe the remaining forces. Avoid the hedgehogs the hybrids throw at you and press forward with quick shots from your Marksman. If you run out of bullets, switch to the Carbine or pick up a Bullseye.

If you swapped out the Rossmore in order to pick up the Marksman, fetch it before going into the second tunnel. After that, follow Capelli into the hallway adjoining the tunnel on the left. Pick up the grenades and stock up on shotgun shells, if necessary.

Tower Entrance
Continue deeper into the tunnel network and drop down into a flooded area. Immediately upon jumping down, a swarm of leapers rushes through the water toward you and Capelli. Clear them out and then head forward to the opening at the end of the hall to the right.

You should now be in a flooded control room. Jump into the water and make you way to the central control platform. Walk around to the back of it and head up the stairs. Reload your shotgun using ammo found there, then hit the door switch. Be aware that as soon as you reach the central platform, leapers begin crawling into the room. Hit the switch and immediately go up the dead end staircases on either side of the platform. From here you can lob grenades at the leapers that group together on the platform, as well as fire at them with the Rossmore.

Meet up with Capelli at the entrance to the next area and help him eliminate the leapers that follow you in; additionally, some will come from the far end of the new area. At the end of this room is the elevator to the top of the tower. Stay still as the elevator climbs. You can fall off and die, forcing you to restart the entire leaper section.

Exit the elevator and move up the two sets of stairs to the right, then hop on the lift to reach the top of the tower. Collect some Carbine ammo and then turn your attention to the center of the tower. You're face-to-face with the Mother Spinner. She's actually not that tough, as long as you avoid her attacks and concentrate your fire. Unload Carbine clips as she circles the the central tower, constantly moving in the process. When she jumps to one of the supporting columns, prepare for her to spit out leapers. You must kill the leapers otherwise they'll hack you to death for the rest of the battle. Remember that the Carbine also has an secondary fire that lobs frag grenade, so use it to quickly whittle her down. It shouldn't take more than a minute to kill here and finish out the mission.

Mission 4: Bryce Canyon
Despite needing inhibitor treatment, Hale decides to risk infection to save Dr. Malikov. He and other members of Echo Team hop on a helicopter and head to the Utah wilderness to extract the good doctor in a desperate effort to halt Chimera plans.
