Slam is a biotic power in Mass Effect 2 and Mass Effect 3's single-player mode.

The power lifts a target and slams them to the ground inflicting damage. Like all powers that knock enemies off their feet, Slam instantly kills Husks.

Crippling Slam[edit | edit source]

    • Lift Duration: 1.30 seconds
    • Slam Force: 600.00 newtons
    • Cripple Duration: 8.00 seconds

Player Notes[edit | edit source]

  • Targets are instantly ragdolled and take double weapon damage until they start to get up. This also applies during the Cripple Duration.
  • Slam hits targets instantly regardless of range; it has no projectile like Throw, Pull, or Singularity.
  • The damage caused by Slam's force can be very inconsistent; sometimes targets are damaged during the lift portion of the power, sometimes during the actual slam to the ground, sometimes both, and sometimes neither (and no damage is done at all). See Talk page.
  • Because Shepard's Slam recharges extremely fast and is instant, it is effective for instantly killing many unprotected husks in quick succession. It is also effective as a general disabling ability against most enemy types, allowing you to cripple them while your squadmates attack the disabled opponents. Slam can provide most of these benefits even at Rank 1, saving squad points to allocate to other powers.
  • Though many biotic powers and other abilities with a force component such as Concussive Shot have no effect on enemies in the process of freezing, Slam is somewhat of an exception to this as the lift portion of Slam will usually work even against freezing/thawing enemies. The damage does not usually seem to apply except against fully frozen targets.
  • Slam can be detonated by Warp if it lands during the lift duration. The small size of this window requires use of squad powers to exploit, however.
  • Slam can be much more effective when used on a target that has already been lifted by another biotic power such as Pull or Singularity. The target will not rise further into the air but instead will be immediately smashed into the ground. This inflicts heavy damage on most unprotected enemies, and it is often enough to kill lesser enemies outright, even on Insanity difficulty.
  • While in the Collector's Ship and Base, a well timed Slam can instantly kill a Collector riding on the mobile platforms to attack you. Simply hit them with Slam and the platform will move out from under them, precipitating them falling into the abyss below. The same applies to missions/assignments with certain low-gravity exterior segments, like Lair of the Shadow Broker and Arrival, where the use of Slam can instantly kill enemies by elevating them high enough to be caught by slipstream, ejecting them from the battlefield.
  • During Legion's loyalty mission, the low gravity means Slammed enemies almost invariably bounce. Thus, as well as causing major damage, Slam will render the enemies helpless and easily picked-off.

Player Notes[edit | edit source]

  • When Slam is used as a finisher to detonate biotic effects, the explosion occurs at the height of lift. This generally limits the biotic detonation effectiveness to other lifted enemies in the vicinity affected by the similar lifting effects produced by Singularity or Lift Grenade.
  • Slam used on a frozen target has less lift, and therefore less damage.
