Objective Achievements
Heavy Metal 10
Survive the bulldozer attack.
You really shouldn't miss this achievement, but it is missable. right at the end of Episode 3 chapter 1 you will get a cutscene showing a bulldozer coming at you. YOU MUST KILL IT! boost you torch at it or pop flares, just keep light on him till hes gone and achievement unlocked. It is possible to just run to the gate open it and finish the chapter. If you do this YOU WILL NOT GET THE ACHIEVEMENT!
Iron Horse 10
Encounter a steam engine.
Same deal as the bulldozer. Don't run past it, kill it! Again you will get a cutscene showing the different parts of the steam engine rising up. You must destroy all of them to get the achievement. This occurs in Episode 3 chapter 2. The steam engine is at the point you must pick up a key to open the door.
Meet the Deadline 30
In "Mirror Peak," make it from the Coal Mine Museum to Cauldron Lake in 30 minutes.
You can go for this on your first playthrough if you want, but i wouldn't advise it. I tried to do it on my first playthrough and you will get stuck somewhere and it will slow you down.
Episode 3, chapter 2. "Mirror Peak" after the cutscene where you enter the museum you have 30 minutes to haul ass down to cauldron lake. It isnt difficult once you know what you are doing. it took me about 20 minutes. Keep moving and if can avoid fighting enemies, do so. Just keep running! Flares are your friend here to make a getaway from a battle. (If i ever get my hands on a capture card ill make a video of this to show you how its done)
Medical Opinions 10
Listen to Hartman's recordings.
At the beginning of Episode 4 when you are following Hartman around his lodge is where you will get this. After you have returned to your room and left to go get the key from downstairs, open the door as normal but instead of turning right into the room where Barry is, turn left into the room full of paintings. You will see a tape recorder on the desk right in front of you. Activate this 3 times (you will have to wait for the recording to finish every time) and your achievement will unlock
Boob Tube 5
See what's on TV.
Shortly after "Medical opinions" you will be chased by the darkness. after ducking into the room on the right because the bookcases are blocking your way you will see you next path block by 2 bear statues. Once past these you will be in a room with a TV right in front of you. Turn on this TV and achievement unlocked.
Child of the Elder God 10
Have a rock'n'roll moment without dropping to a low health state.
One of the slightly more tricky achievements in the game, but easy all the same. Towards the end of Episode 4 you will find yourself on stage fighting off taken in a very Left 4 Dead 2 fashion. from the second you are the that stage until you see the fence blow up you cant go into the low health state, which is recognizable by your screen turning black and white. if this happens just reload last checkpoint.
Once on the stage grab as much stuff as you can, namely the pump action shotgun and the flares. If you have time get the heavy duty lantern too. Now just fight off the taken by any means. If you see the stage light come on run under it for a checkpoint. After the fence blows up you should get it.
To make it a lot easier on yourself, do this on Normal
Drink 'Em Both Up 10
Put de lime in de coconut twice.
This is a 2 part achievement you will start in Episode 1 and finish in Episode 5.
Once you arrive in Bright Falls and walk into the diner head to the left and you will find a juke box. Activate the juke box and then kick it to get it moving. Once you here the tune you are done with step 1.
Proceed with the story until you get to Episode 5 where you are moving through the town again with Sheriff Breaker. You will see the diner again eventually. Go in and activate the same juke box again. 10 more points to add to your score!
An Idyllic Small Town 30
Make it through "Night Life in Bright Falls" in one go without dying or restarting even once.
A lot easier than it seems. Episode 5 chapter 1 is where you want to be. You will be with the sheriff the whole way who has a heck of an aim so she is your best friend here. keep close to her and use flares when needed. the only tricky parts are outside the church and at the helipad. the church is easy enough because the sheriff is helping you. Just concentrate on ones near you and pop flares if they start to swarm up on you. Be careful about the fast moving ones, they can creep up on you at any time.
The helipad is a little harder because the sheriff is in the chopper so your on your own. luckily there is LOADS of supplies. so before you trigger the cutscene by walking up to the helipad, gather up as much stuff as you can and get ready for a fairly lengthy fight. Flashbangs here will help hugely. once you get in the chopper and fly away you are done and 30g better off for it.
Gunless Wonder 30
Make it to Cauldron Lake without firing a single shot in "On the Road to Cauldron Lake."
Again, not very hard at all. I managed to do this on my first playthrough. On Episode 6 you cant fire a single shot ever. You are limited to flashbangs, flares and your torch. Luckily they are everywhere. You are going to want to avoid combat as much as possible and just go from checkpoint to checkpoint as quick as you can. You can also use your car headlights, so stay in the car for as long as you can, only get out when you have to and proceed to run down anything that moves.
Tip for the battle with the big searchlight in the middle of the ghost town: Pop a flare next to the cart you need to push and push. when it runs out pop another one. This way you wont need to fight the huge amount of enemies that come after you. This method can be applied anywhere in the game and id recommend it for certain spots on Nightmare too.
