Cheats:
Infinite Battery Energy
Alter game files at your own risk and always create backups. To obtain infinite battery energy, follow these steps:
Navigate to your Outlast settings: C://Users//[your username]//Documents//my games//Outlast//OLGameConfig
Look for OLgame.ini within that folder and open it with Notepad or a similar text-editing program.
Search for "bat" (without the quotation marks) and that search should lead to a series of lines in the file that appears about as follows:
OLGame.OLCheatManager]
bCheatsEnabled=false
bUnlimitedBatteries=false
Update the setting of the second and third lines so that they read "true" instead of "false" and save the file. When you play next, you'll have infinite battery energy.
Invincibility Hack
Alter your game files at your own risk and ALWAYS make backups!
Navigate to C://Users//[your username]//Documents//My Games//Outlast//OLGameConfig and you will see a file named OLEnemy. Open it and then make some changes.
As you scroll down, you'll find things under titles such as [OLGame.OLEnemyPawn] and [OLGame.OLEnemyGenericPatient_G]. These are enemy titles that contain codes such as NrmAttackNormalDamage=51, NrmAttackThrowDamage=51, HardAttackNormalDamage=101, HardAttackThrowDamage=101, and so forth.
You want to change those values from their current numbers to 0. There are quite a few to change, so the process could take quite some time. Make sure that you only change digits that relate to the values specified above. The end result once you change all appropriate entries is that no enemies will be able to inflict any damage.
Go to "C:\Users\[your username]\Documents\My Games\Outlast\OLGame\Config".
Open the file "OLEnemy.ini" with Notepad. Change all of these speed and damage settings.
NormalSpeedValues=(PatrolSpeed=10,InvestigateSpeed=10,ChaseSpeed=10)
DarknessSpeedValues=(PatrolSpeed=10,InvestigateSpeed=10,ChaseSpeed=10)
ElectricitySpeedValues=(PatrolSpeed=10,InvestigateSpeed=10,ChaseSpeed=10)
AttackNormalDamage=0
AttackThrowDamage=0
Note: 10 was very slow so you may want to set it at 15 or 20.
It took for ever for the enemies to move enough for me to pass by them.
Also in same folder open "OLGame.ini"
BatteryDuration=999.0
DefaultNumBatteries=88
MaxNumBatteries=99
Outlast Tips:
Play with the lights out in complete darkness to make Outlast much scarier, like you'd expect from a horror game.
Cheats:
For all those trying to survive the horrors that be in outlast I have found a way to make those batteries last a long time as well a way to be a little less heard while walking about jumping and landing hard and walking in the sewer waters, this is what you do. Open your outlast location and look for the OLGAME folder then config. Go down and see default game.ini the .ini is hidden, open default game with notepad and you go to edit and find, then type the word batteries first. you will see bunlimitedbatteries=false make this say
true. just above where you found this unlimited batteries you will see bcheatenabled=false make this true. then hit find next you will see defaultnumbatteries=2 make this 10 then hit find next you will then see maxnumbatteries=10 you can change this to 20 -30 -40 but
10 is enough for now and I will explain. next go back to edit and find and type in Battery Duration this is set to 150.0 make it= 999.0 or what ever. I find that 999.0 is plenty along with those 10 batteries, now in this list you will also see WalkingLoudness= and so on change these but of course make a back up in case you screw up. and there you have it a way to survive the mental crazy horrors that be, you can set your run speed to out run those crazies, and your walking noise and running noise and crouching noise, landing noise water walking noise and so on, well enjoy this cheat and win the game.
