A Vision Blocker is a type of ability that blocks line of sight of an area on the map.
A vision blocker ability is used to block line of sight on an area of the map. This allows allies to carry out actions behind or inside the blocking object without giving visual info to the enemy on the other side, such as moving between positions. Players should be wary that most vision blockers are not solid however and allow gunfire to pass through, so if an enemy hears anything happening they may start to fire through the blocker in the hopes that they will tag or even kill their opponents whilst they are behind or within it.
For most vision blockers that allow agents to pass through, their vision will gradually decrease until it is completely covered in a colored, opaque screen as they enter at the edge of a blocker, with the reverse happening as they exit an edge.
General Vision Blocker abilities
INSTANTLY toss the cyber cage in front of Cypher. ACTIVATE to create a zone that blocks vision and plays an audio cue when enemies pass through it.
EQUIP a chemical sprayer. FIRE to spray a chemical cloud in all directions around Viper, creating a large cloud that reduces the vision range of players and maximum health of enemies inside of it. HOLD the ability key to disperse the cloud early.
A smoke is a spherical vision blocker. Players are unable to see what is directly behind a smoke but can walk through them. Most smokes deploy on the ground as a hemisphere, but the functionality of a smoke or the elevation of the map around the deployment area can cause a fully spherical smoke to form. This can be useful for creating "one-ways"; smokes that are positioned in such a way that the user and their team can see part of an enemy's body beyond the outer edges of the smoke but the enemy's vision towards them is completely blocked.
Place Stars in Astral Form.
ACTIVATE a Star to transform it into a Nebula (smoke).
USE a Star to Dissipate it, returning the Star to be placed in a new location after a delay.
Dissipate briefly forms a fake Nebula at the Star’s location before returning.
EQUIP a tactical map. FIRE to set locations where Brimstone's smoke clouds will land. ALTERNATE FIRE to confirm, launching long-lasting smoke clouds that block vision in the selected area.
INSTANTLY throw a projectile that expands into a brief vision-blocking cloud on impact with a surface. HOLD the ability key to curve the smoke in the direction of your crosshair.
EQUIP a shadow orb, entering a phased world to place and target the orbs. PRESS the ability key to throw the shadow orb to the marked location, creating a long-lasting shadow sphere that blocks vision. HOLD FIRE while targeting to move the marker further away. HOLD SECONDARY FIRE while targeting to move the marker closer. PRESS RELOAD to toggle normal targeting view.
EQUIP a gas emitter. FIRE to throw the emitter that perpetually remains throughout the round. RE-USE the ability to create a toxic gas cloud at the cost of fuel. This ability can be RE-USED more than once and can be picked up to be REDEPLOYED.
A wall is a linear or rectangular vision blocker. Players are unable to see what is directly behind a wall. Most walls allow agents to walk through them and throw utility through them but some are solid and will block agents, utility, and gunfire.
When Cosmic Divide is charged, use SECONDARY FIRE in Astral Form to begin aiming it, then PRIMARY FIRE to select two locations. An infinite Cosmic Divide connects the two points you select. Cosmic Divide blocks bullets and heavily dampens audio.
EQUIP a flame wall. FIRE to create a line of flames that moves forward, creating a wall that blocks vision and damages players passing through it. HOLD FIRE to bend the wall in the direction of your crosshair.
FIRE two energy lines forward on the ground that extend a short distance or until they hit a surface. The lines rise into walls of static electricity that block vision.
EQUIP a barrier orb. FIRE places a wall that fortifies after a few seconds. ALT FIRE rotates the targeter.
EQUIP a gas emitter launcher. FIRE to deploy a long line of gas emitters. RE-USE the ability to create a tall wall of toxic gas at the cost of fuel. This ability can be RE-USED more than once.
