The third is in plain sight after exiting the building to enter the final battle of the mission to help Shepard fight waves and waves of enemies. The second is near a locked door that opens after defeating a wave of Collectors.

The first is at the very beginning leaning on a stasis pod in the open to the right of a building. It pops up in three different locations, but if you miss these, you'll receive it at the end of the mission anyway. This weapon can be found during the main mission on Horizon. Its codex entry also references DRM as it is supposedly difficult to duplicate because of its Fabrication Rights Management (FRM) tech. This weapon is usually seen among Blue Suns mercenaries, and unlike the Vorcha and the Grenade Launcher, they actually use this weapon in-game. The ML-77 Missile Launcher is a pretty useful weapon, even if it's not as explosive as the M-100 Grenade Launcher.

Like the Grenade Launcher, the ML-77 Missile Launcher also has bonus damage against armor, shields and barriers. Hopefully, this is fixed in the Legendary Edition. It can do serious damage thanks to its ability to head straight for its target, although it doesn't quite seem to work this way for Shepard. The first upgrade can be bought for 2500 Iridium. These upgrades are obtained at various points in the game depending on your order of doing missions and whether they're found. This heavy weapon is accessed after upgrading Heavy Weapon Ammo once on the Normandy and costs 5000 Iridium.

It doesn't do a ton of damage, though, making it more of a utility weapon.

Since it's electric, it works best against synthetic enemies and shields, although it can damage organics without protection and stun them. It's a unique weapon that shoots an arc of electricity at a target that can also jump to nearby enemies. This weapon is one of the many things Cerberus was working on and was finally tested during an encounter against the Geth. In the original release, Shepard receives an email from Illusive Man about the weapon and how it was obtained afterward, it will appear in Shepard's arsenal. It's unlikely this service will be part of the Legendary Edition, so the Arc Projector will likely be given to the player after the prologue quest or first encounter with the Illusive Man. This one was obtained by simply signing up for Mass Effect 2's Cerberus Network, a news service that originally came with the game.
