Gravity Well is a Plasmid introduced for the Minerva's Den DLC for BioShock 2. It allows Subject Sigma to throw a superdense polyp which then bursts after a moment (upon impact if it hits an enemy), sucking in nearby objects, corpses and enemies into a swirling vortex of destruction.

Strategy[]

  • When thrown, the Plasmid will bounce upon contact with the scenery, and will only detonate after a set amount of time (around one and a half seconds). If thrown at an enemy, it will automatically detonate.
  • Although the Plasmid doesn't deal damage on its own at level 1, enemies will take damage whenever they collide with another object, and its recommended to fire this Plasmid in the middle of a group, as it will attract every enemy towards it, causing affected enemies to collide into each other and take large amounts of damage, in conjunction with objects in the room.
  • Stunned enemies will be splayed across the floor, making it difficult to land a headshot. Try laying a Gravity Well in front of the target, so that they fall flat on their face and expose it to the player.
  • Gravity Well can pull enemies through certain walls, although it won't damage them.
  • Avoid firing this Plasmid around if there are friendly Bots nearby, as it will drag them in and potentially damage them too.
  • Electromagnetic Locks can be disabled by this Plasmid.
  • One can also create elaborate traps using Cyclone Traps to send enemies flying into the Gravity Well, which can then lure them into spaces full of objects to send them on a damage-inducing collision course.
  • The Shotgun is recommended as a weapon to use in conjunction with this Plasmid due to how it can do massive amounts of damage up close, and with enemies not being able to attack Subject Sigma, it's a very safe and fast option to get out of most hassles.
  • Due to this Plasmid also being a "getaway" Plasmid, it's recommended to use it when battles become too hectic in order to escape.

Recommended Tonics[]

  • The EVE Saver line of Tonics reduces the EVE cost of using Plasmids.
  • Drill Specialist greatly decreases the Plasmid's EVE cost, but limits the player's weapon selection to the Drill.
  • Fountain of Youth restores Health and EVE when in water, which can allow constant (and free) use of this Plasmid.

Behind the Scenes[]

  • The game files also list this Plasmid as "Vortex" and "BioGrenade."
  • A "gravity well" or "gravitational well" is a conceptual model of the gravitational field surrounding a body in space. The more massive the body, the deeper and more extensive the gravity well associated with it.[1]
