Act 1: The Mechanic

After investigating the garage and talking to Emma, you will be tasked with finding the 3 objects. They are all easy to find since indicated on your mini map. Once you obtain them and talk to Emma again, you must go "rewrite reality". Go to the spot on the map and put the CD in the boombox, valve in front of the oil (turn the valve) and then the battery in the switch (turn on switch)

Act 3: United

Once you finish the last scene this will automatically unlock. Watch through the entire credits to watch one more scene.

Arcade mode is essentially a "wave" based game type. Enemies will get more difficult and increase in quantity as you play. To gain this achievement you must survive the whole level for 10 minutes. You can get this achievement along with "Skill Beats Gun". See that description for an easy way to get both.

In arcade mode you not only have to get a ton of points, but also not get hit for 6 minutes. Within the period of not being hit, you must score this 100,000 points. You can go over the 6 minutes for the points of course, just can't be touched. This can be one of the most frustrating achievements in the game!

There are 5 levels each with a Nightmare Mode version.

• Cemetery
• Ghost Town
• Oil Field
• Caves
• Trailer Park

The levels will all be locked except one when you first start out. As you gain stars, you will earn the levels. Your goal is to hit 24 stars between all 10 levels. That is 24/30 possible. You will need 3 stars on every regular level and 9 more between the Nightmare ones. You will have to get a 3 star on at least one Nightmare stage. The score you will need to shoot for is around 40-45k specifically for Nightmare. Just try to kills enemies as fast as you can to gain the most amount of points. You don't have to survive the full 10 minutes to get 3 stars, but it sure helps (bonuses and the sun kills remaining enemies). Just keep on your feet and always look behind you. You will have to get very good at dodging. The more familiar you are with a level the better you will be. So if you are failing, just keep trying until you start perfecting it. Do not worry about any other arcade based achievements until you have unlocked all levels. By this time you will be better at it and know what to expect.

To survive an arcade level, you must complete the full 10 minutes of it. Waves of enemies will come at you but you cannot shoot them. You will have to utilize flares and your flashlight to keep them away. The best thing to do is to keep away from the initial Taken that spawn in a level. This means you'll be running from and dodging the same Taken the entire time. This will simplify the achievement.

First you must unlock a Nightmare Arcade by gaining at least 12 stars within the available levels. Nightmare is a bit tougher. Enemies take about double the shots to kill them. Also, there are no waves. They just keep coming without you having much time to prepare. Because of this, you should get a lot of points. This is suggested after you have unlocked all Nightmare levels and know which one you are best at. You will need to know where everything spawns, and stick close to an ammo drop. So make your rounds early to pick up flares, guns, and flashbangs. Then camp around at an ammo pickup.

A splitter is an enemy who physically splits into two enemies or more, creating a clone of itself. It basically multiplies. What you need to do is kill two at once with one shot. The first time you see this enemy is the perfect time to get the achievement. When going for the item near the train tracks during the "Find items for rewriting reality" objective, this enemy will jump out from the door of a building you are supposed to enter. The game will inform you of this new enemy. Shine your light on it and to make it easier, let it split again. Now you will have 4 enemies to shoot at. Take your shots. If your achievement doesn't unlock, just reload your last checkpoint. It will put you right in front of the building again. You can always get it later, but it's nice to get it out of the way here.

Manuscripts are a type of collectible in this game. You read them for some extra story content. You can keep track of these pages by selecting "Collectibles" from the main menu and going to "Manuscript Pages". It will show you the 3 areas in the game which you can check. Collecting these will let you unlock guns in story mode and some things in arcade as well. While in the game you can press or via the start menu look at what collectibles you have obtained. You can replay chapters from the main menu to pick up the ones you have missed. If you do this, it's suggested to do it after completing the game so that you don't over write your checkpoints. The manuscripts will appear different depending on which Act you are in, so that is something to pay attention to if following a guide.

This is accumulative between both Story and Arcade modes. Taken are the enemies of the game (human overtaken by darkness). You will likely get this while finishing up your achievements in Arcade Mode. If not, just keep replaying until you get it.
