I. NIGHTVISION AND EXTRAVISION

Some maps in Purge have extreme dark areas. To see in the dark, characters have either Nightvision or Extravision. There is no limit to using Nightvision or Extravision; it stays on for as long you like. By default, this actived by the V key.

Characters of the Order have Nightvision. This amplifies the ambient photons in the area allowing the player to see everything in green in the dark. While it has some visual noise (grainy static), Nightvision can used in most daylight or bright areas too to help spot hiding players. In most cases, Players can choose leave Nightvision on the entire time, however it will get washed out in really bright areas. Also, Nightvision is weak in absolute pitch darkness when there is no form of light at all to amplify.

Since the Chosen don't have the optical cybernetics or googles for Nightvision, their magic researchers invented an ability called Extravision. While Extravision allows the Chosen to see in the dark, it is not functionally identical to Nightvision. Instead of enhancing what exist, like all of magic, Extravision changes the very rules of light and dark. For this reason Extravision is often called "Inverse Vision". It flips light to dark and dark to light, resulting in a blue monocrome image with low visual noise. This makes it excellent in dark areas. The darker some area is, the brighter it is with Extravision. However, Extravision is almost useless in bright areas as everything will "wash-out" and turn dark.

II. ZOOMING

The special vision of the Order and the Chosen has one additional ability. All characters have telescopic vision in their eyes. By simply pressing your zoom key (default Z key), players can zoom while wielding any weapon. This helpful not just for sniping, but for scouting for dangers on outdoor maps. Commandos wielding their scoped rifle have an additional zooming ability.
