Valorant
Sage barriers can lift players onto boxes, doorframes, and ledges that defenders or attackers are not expected to hold. Many boosted off-angles have been removed or adjusted.
Omen, Brimstone, Astra, and Viper have all had setups where smoke placement favors the defender's vision while obscuring the opponent. These are among Valorant's most common visibility exploits.
Jett can combine vertical mobility with map props to hold elevated positions that are difficult to clear using standard crosshair placement. This creates exploit-like geometry pressure.
Some patches allowed Cypher cameras to be hidden inside map seams or on unintended surfaces while still relaying vision or darts. Riot has patched many of the strongest placements.
Turret placement near thin ledges or objects sometimes gave it sightlines or survivability beyond intended positions. These exploitative setups were prized on certain maps.
