From Clogopedia, the Natural Selection 2 wiki
The Alien Vision highlights Players and Structures and gives the Aliens a huge advantage when fighting the Marines.
Alien Visions can be found in:
- NS2+ Options - UI : You can choose between several Alien Visions or modify your own with CrazyAV (Note: CrazyAV takes quite a toll on a mediocre GPU!)
- Steam Workshop Mods (have usually better performance)
Steps to activate them:
- Subscribe to a Mod
- Activate the Mod in the Mainmenu of NS2: Mods
