PC Tweaks (Mass Effect 3)

Mass Effect 3 is based on Unreal Engine 3 and many settings can be modified in a way similar to Mass Effect and Mass Effect 2, allowing the user to mod, tweak or cheat.

Coalesced.ini
Setting the highlight distance to make it easier to find interactable objects:

Biogame.ini/sfxgame/bioplayerselection/maxhighlightrange=800

800 is default, 8000 works nicely and highlights objects far enough out to cover your visible range easily.

Increase the Maximum fuel the Normandy can have:

Bioweapon.ini/sfxgame/sfxinventorymanager/maxfuel=1000

1000 is default, 10,000 works well enough to let you scan without stopping to refuel constantly while not taking forever to refuel when you do.
