How to complete Crab Key

Here is the video: https://www.youtube.com/watch?v=2T-BlBmlolE

At the very beginning I throw a grenade at a roughly 45 degree angle straight forward. This grenade usually kills one or two bad guys that can really get in my way. Then I aim slightly to the left of the first enemy since the auto aim likes to go to the guys in the background. Pick up his AR-4 and kill the remaining enemies with it. If you run out of bullets, pick up another AR-4 instead of reloading the one you have, unless there are no other AR-4's nearby. Press A on the terminal and then hack the terminal across the bridge to lower it. Kill the enemies that I kill since they are the ones that get in your way most often. Once you make the next right turn after the bridge, there are going to be several enemies on your next right. One of them has a heavy machine gun. Kill him along with as many other ones as possible without losing too much time. Then kill the next two bad guys and go into the building. Use your shield before you go inside since there is a helicopter that will hurt you pretty badly.

The next room is pretty self-explanatory. Just kill the enemies and reload before going to the next half of the room. The final part of this room is very challenging. I just use what's left of my shield and get out of there as quickly as possible. When you get into the next room go up the stairs and press the button on the top floor. On your way down there will be a guy with a Mag-rail and a Venom gun. Pick both of them up and go into the next room.

Shoot the Mag-rail as soon as you get into the next room since it will almost always kill someone if you have auto-aim on. Stun the next guard you see and punch him to kill him instantly. Kill the guy on top of the large box then the guys on the ground level. I like to stun one person, shoot someone, then punch the guy i stunned. I feel like that is pretty efficient. The Mag-rail can do collateral damage if you can get two enemies to line up properly. I managed to do that in this video. Once you get rid of all the enemies in the first half of the room, reload (if you need to) then do the same thing to the enemies in the second half of the room. Stun, Shoot, Punch. Sometimes one of the guys will have a second Mag-rail. If you see it, replace the venom gun with it.
 (Note: One of the enemies in the second half of the room will always have a heavy machine gun. If you try to run through the room without killing him you will almost always die)

Once you get outside there will be an enemy on the right side that you can shoot. If you still have the venom gun, shoot him with that and punch him. There will be a gate that opens and four enemies will run out. Keep in mind that the running animation is scripted so you can't do damage to them during that animation. Wait for a short time then use the mag-rail and you should kill at least two of them. Getting a collateral here is extremely easy. I killed all four of them with two Mag-rail shots. If you don't have dual Mag-rails, pick one up here. Do not go through the gate until you have dual mag-rails with a good amount of ammo. Once you go through the gate, two helicopters will spawn. They only take two shots with the mag-rail, so press L+R to kill them. One of the helicopters will fly directly over you, so you can kill that helicopter in one hit since it's so close to you. Once you kill the helicopters, go through the next gate and use your shield so you don't take damage from the two enemies that leave that same gate.

The next part is pretty easy. Just keep going along the path until you get to the elevator. Use your shield ability to conserve your armor. Don't worry about using too much eye power. Your eye power regenerates and you don't need it for anything any time soon. Shoot the first guy in the caves and it should kill the person behind him as well. Just keep going straight and shooting any bad guys in your way. Like I said, this part is pretty easy and self-explanatory. You are most likely going to run out of Mag-Rail ammo before you exit the caves. Just pick up a gun from any enemy you killed and keep moving. The last enemy in the caves has an HS-90 and a Mag-Rail. Pick up both of them.
(Note: It's better to have the mag-rail in your right hand for a part later in the level. you will be able to use it while riding along zip-lines if it's in your right hand)

After leaving the caves, Shoot every enemy you can with the HS-90. start using the mag-rail while you're reloading the HS-90. By doing this you will be able to shoot enemies constantly. Start using your shields once you go under the dump truck and kill as many of the enemies as you can without losing too much time. Go down the zip-line as soon as possible. You can snipe some enemies with the Mag-rail while you're on the zip-line. Be sure to use grenades to kill any remaining enemies before continuing. There is a guard with a rocket launcher on the stairs below you. Be sure to kill him before you do the skip in the video shown below.

After the Zip-line, Do the Crab Key Kirch Skip. A detailed video of this skip can be found here: https://www.youtube.com/watch?v=y4HhzFQNxLI

Kill the four enemies that spawn in the tunnel and pick up an AR-4. There will also be an enemy behind you but he doesn't always shoot at you. Kill him if necessary. Going through the tunnel is a great time to regenerate health and reload your weapon. Kill the next three bad guys and pick up Predator MG (the heavy machine gun). Continue to mow down the next group of bad guys. Keep holding the trigger because more enemies will come through a nearby door. Pick up another AR-4 from one of the guys you killed and keep moving. Pick up some armor here if you don't have any. Like I said earlier, enemies don't take damage while they're doing a scripted running animation. The next three guards will do that so you can run right past them if you're quick enough. I wasn't quick enough in the video so I had to kill them. 

There is a huge group of bad guys immediately after this. Start shooting at them and kill as many as you can. One of them should have another AR-4 so you can pick it up instead of reloading. If you have to reload, hide behind one of the nearby boxes. There are more enemies at the top of the stairs so be sure to kill them quickly. One of them can have a rocket launcher so you don't want to be too slow. (This is a good place to wait and regenerate health if you have to.) Pick up another AR-4 if you can, or reload the one you already have and run across the next bridge. One of the enemies at the end of the bridge has a venom gun so be sure to kill him quickly. Use your shield if you need to. Run past the next group of enemies while shooting at them. One of them has a shield so just run past them. Go through the large gate and reload your AR-4.

When you go through the large gate and the end of the tunnel there will be a guard with a machine gun and a shield. For some reason his shield doesn't seem to work properly because you can kill him just like a normal enemy, even though his shield is clearly visible. Just tap R multiple times instead of holding it to make your accuracy at range slightly better. Drop your weapon as soon as you kill him. (To do this, hold R+A on the Gamecube version). There will be a rocket launcher to your left. Pick it up and start shooting at the tank on the right side. Never stop moving. Always be moving left and right to avoid the tanks firing at you. The rocket launcher will always respawn at the same place on the ground so you can pick up another one as soon as you're out of ammo in the one you currently have. Each tank takes four rockets to kill. Keep repeating this until both tanks are dead. Use your shield and move toward the next large door to finish the first section.

Section 2 is much easier than section 1. Sometimes you start with the default pistol and sometimes you don't. I'm not sure what causes this or why it varies, but I usually have the default pistol at the beginning of section 2.

Start off by strafing through the long hallway and throw a grenade at the door to kill a group of two enemies. Pick up the Venom gun and go into the next room. Shoot the guy to your right and punch him to kill him instantly. Then throw two grenades. One in the middle part of the room and one toward the next large door. They two grenades should kill two or three enemies. Go to the center of the room and press the button and quickly go to the next hallway. You will see a huge group of enemies, but just use your shield and run past them. They can't go through the door so you're safe when it closes. Keep going until you get to the part where you have to destroy Dr. No's aircraft. There is a set of armor at the end of the room along with a Mk2 Detonator. Pick that up and use it to blow up Dr. No's aircraft. It takes a lot of hits so be patient. Another Mk2 will eventually spawn in the same place so you can dual-wield them. Keep shooting Dr. No's aircraft until it explodes. Then move on to the next room where you will get to fight Dr. No himself.

Press D-pad up to select your hacking ability and hack the six green terminals in the center of the room. You can only hack two at a time with full eye power so you'll have to wait for a long time for your eye power to regenerate. You can easily camp in a corner until your eye power regenerates. The Dr. No fight seems hard at first but it's really easy once you know that you can just sit in a corner and wait. There is also a lot of armor in the rooms on the side. Wait for your eye power to regenerate half-way and hack a terminal. then go back and camp until your eye power regenerates half-way again. Keep repeating this until all six terminals have been hacked.

Sometimes enemies can get in your way. The Mk2 detonater is a pretty good gun, actually. It fires sticky grenades that you can detonate by firing again. Do this to kill an enemy that spawns with a heavy machine gun and pick it up. Use this to constantly shoot Dr. No until his shield breaks and he dies. Sometimes Dr. No can be a troll and hide behind the pillar in the center of the room. There isn't really anything you can do about that, unfortunately. Just move around until you see him again and keep shooting until he dies.

Once Dr. No is dead, go down the ladder and go down the hallway with the brown walls. (The rest of the hallways have grey walls). Keep moving down the long hallway and complete the mission!
