Denial Bursa

Denial Bursa is one of the three types of Bursa introduced in Operation False Profit, which specializes in zone control and lockdown attacks. The back side of a Denial Bursa holds a hackable console, which can only be accessed only after the Bursa is defeated, and which allows Tenno to turn it against the enemy for a short duration before expiring. Having been added as regular enemies in, they have a high chance of spawning on Pluto, Neptune, Europa, Jupiter, Mars, and Venus, whenever alarms are triggered in a Corpus mission.

Tactics

 * Denial Bursas operate by finding a choke point between map tiles (i.e. doors) and then creating a row of energy bars that prevent Tenno from advancing. Trying to walk through said bars will deal heavy damage with its proc, along with a Dispel to any buffs currently applied.
 * The projectors from which the bars originate can be destroyed with weapons fire and certain Warframe abilities such as Valkyr's Paralysis.
 * The Bursa will often loiter near said field, using its Shockwave Bash to knock players into it for almost certain death. As such, it is recommended to destroy the field projectors first.
 * Of the three Bursas, this behavior makes the Denial Bursa a defensive type.
 * The Denial Bursa is mostly armed with utility firearms: Its primary weapon shoots a special orb which emit energy beams that slow down nearby Tenno, and it occasionally fires beams to blind up to two Tenno. It is also equipped with missile launchers that can fire a volley of explosive missiles against enemies, similar to Jackal's missiles.
 * Denial Bursa uses two Riot Shields which it can deploy by huddling them together to prevent being stunned or knocked back by Warframe powers and abilities. Deploying the shields hinders the Bursa's mobility however, preventing it from moving.
 * Denial Bursa emits a short-range aura that reduces armor and slows down shield regeneration.
 * Denial Bursa has increased resistance against stunning and crowd control abilities.
 * Rhino's Rhino Stomp will affect the Bursa, however will recover quicker than other units.
