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."
- Unlocked at the Normandy research station after two Heavy Weapon Ammo upgrades have been researched. Costs 15,000 iridium.
Player Notes Edit
- 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, most enemies, even heavy enemies 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.
- Shots from the Avalanche will briefly stagger most enemies that can be staggered, even if they still have protection such as shields or armor.
- The Avalanche produces a large blast radius of 5 Meters, making it easy to hit enemies without direct line of sight.
- The freeze effect of the Avalanche is uniquely long, lasting about 25-30 seconds, making it the longest disabling effect in the game by a large margin. This duration appears unaffected by any upgrades or research. 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 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.
- The projectile fired by the Avalanche can sometimes ricochet off of squad members.
- 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.
- Remember that many biotic and other abilities with a force component such as Concussive Shot have no effect on enemies in the process of freezing, though fully frozen enemies are still affected.
- 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.
