ME2 HW - Grenade Launcher
Heavy Weapons are a class of weapon designed to deal destruction greater than conventional means. These weapons typically damage through all types of protection but suffer from high power consumption, making their usage situational but devastating given the right conditions.

Heavy Weapons are available to all player classes in Mass Effect 2 and Mass Effect 3.

Mass Effect 2 Edit

Rather than the universal thermal clips utilized by smaller weapons, heavy weapons consume power cells that can be found on missions. The ML-77 Missile Launcher, M-622 Avalanche, and M-920 Cain are researched within the Normandy SR-2's tech lab upon acquisition of enough Heavy Weapons ammunition upgrades; the others can be found during missions.

Some of the heavy weapons will cause damage to Shepard or the squad regardless of difficulty setting especially if fired at point blank range. The three heavy weapons that can cause "friendly fire" damage are the M-100 Grenade Launcher, the ML-77 Missile Launcher, and the M-920 Cain. Note: Squadmates may complain that Shepard is hitting them with friendly fire if they are in the field of fire or close proximity when Shepard is firing with any weapon, however they will do this regardless of whether they're actually taking damage or not.

All of the heavy weapons in Mass Effect 2 have a longer switching animation than other standard weapon types. This extra time applies both to unlimbering the weapon and for putting it away or "holstering" it. Shepard's movement speed is also slowed considerably during the switching animations.

Mass Effect 3 Edit

In Mass Effect 3, heavy weapons are no longer available to be equipped at the armory. Instead, they are picked up on the battlefield and thrown away after their limited ammo has been depleted. Despite the scarcity of heavy weapons, however, they remain exceedingly powerful, with some capable of destroying the toughest enemies instantly or eliminating whole enemy squads at once.

In the single-player campaign, switching weapons will cause the heavy weapon to drop in front of you. It can be picked up at a later time (provided it still has ammunition). In multiplayer, the weapon will be replaced on the player's back.
