The M-622 Avalanche is a heavy weapon in Mass Effect 2.

Description Edit

Cryo Round technology is used to modify standard weapon slugs. A cooling laser collapses the ammunition into Bose-Einstein condensate, a mass of super-cooled subatomic particles capable of snap-freezing impacted objects.

Normandy's scientists have found a way to apply this technology on a large scale: by generating a mass effect containment "bubble," this proof-of-concept large weapon technology is effective against armor, shields, and biotic barriers. It is nicknamed the "Cryo-Blaster."

Acquisition Edit

  • Unlocked at the Normandy research station after two Heavy Weapon Ammo upgrades have been researched. Costs 15,000 iridium.

Player Notes Edit

  • Unlike other heavy weapons, having the Avalanche selected does NOT slow the player down.
  • The Avalanche can hold twice as many rounds as the M-100 Grenade Launcher and has a faster rate of fire, allowing many rounds to be fired in quick succession. Once its multipliers against barriers, shields, and armor are taken into account, its damage per shot is also comparable especially on higher difficulties where most opponents have protection on top of health.
  • Repeated hits will strip off shields, barriers, and armor. Once unprotected, enemies, even heavy ones like YMIR Mechs and Geth Primes, can be frozen leaving them open to further attacks from which they will suffer double damage. Husks will die spontaneously upon freezing.
  • The Avalanche produces a large blast radius of 5 Meters.
  • The freeze effect of the Avalanche is uniquely long, lasting about 15-20 seconds, making it the longest disabling effect in the game. Warning: hitting an already frozen enemy with the Avalanche does NOT refresh the duration of the freeze, a frozen enemy (if not killed) will thaw and recover based on when it was first frozen.
  • The Avalanche fires projectiles that arc slightly with gravity so aiming can take a bit of practice, but this actually makes it somewhat easier to hit opponents on higher ground or behind cover.
  • The Avalanche can be fired rapidly or charged up, although a charged blast is no different from a non-charged blast.
  • Frozen enemies can still regenerate health, such as Vorcha.
  • The M-622 Avalanche does not cause any type of friendly fire to Shepard or Shepard's team regardless of difficulty setting, allowing it to be fired at point-blank range safely (one of four heavy weapons capable of this).
  • The projectile fired by the M-622 Avalanche can sometimes ricochet off of squad members it is fired at.
  • The weapon is particularly effective in many harder fights on the higher difficulty levels as it can take entire groups of enemies out of the fight for an extended period of time. In many difficult fights new enemies will immediately respawn to replace any that were killed. Freezing enemies instead of killing them outright prevents this and reduces incoming fire, letting you focus on a hard target or reach an objective safely.
  • This weapon is effective with Grunt in your squad as his charge may then shatter your frozen foes. Conversely it can be less effective with biotics like Jack in the squad as biotic abilities and other abilities with a force component often have less effect on frozen enemies.


Trivia Edit

  • Although holding the fire button charges up the weapon, it does not have any effect on the weapon. This could possibly have been an early feature that was removed.
  • The Avalanche, like many other Heavy Weapons from Mass Effect 2, was originally intended to appear in Mass Effect 3, as a screenshot shows Shepard using it on an Atlas during the Sur'Kesh mission, but it was cut late into development. The heavy weapons that were cut still remain in the game's coding.
