Get Rid of the Orange Scope When Using the Laser Designator
In level 8, (Forging a Path) your character uses a Laser Designator to call in artillery strikes against the Helghast. Particularly since it's daytime, the orange scope makes seeing the enemy all the more difficult, and you can't see as far. To get rid of it (And make it easier to see) equip the weapon in the weapon cycle that's before the Laser Designator (So that when you press O it will switch the Laser Designator). Press O to switch to the Laser Designator and immediently sprint forward (L3 is to sprint). If done correctly, the orange tinted overlay should be gone.
