Firefight:

Players will soon be able to arm themselves with the Firefight Pack, a new Single Player Weapon Pack available for download August 7 for $2 or 160 MS points. The Firefight Pack will feature two powerful new weapons and five bonus weapons to use in the fight to Take Back Earth!

Indra Sniper Rifle: Fully automatic sniper rifle.

• The Indra’s low-powered scope leaves it most effective at medium range, but many soldiers believe this limitation is offset by the gun’s rapid rate of fire. The Indra is the first military-grade, fully automatic sniper rifle. It has an extremely efficient heat-sink system that allows a surprisingly large number of shots to be fired before the weapon ejects its thermal clip.

Krysae Sniper Rifle: Heavy turian sniper rifle with explosive rounds and an automatic scope for all-range fighting.

• This turian antimateriel rifle is modified to kill Reaper enemies. The Krysae’s scope uses a rangefinder that adjusts to keep the target in proper proportion to the shooter, which comes in useful when the sniper is forced into close range. Its specialized ammunition is both armor-piercing and explosive. In a desperate move, the turians released its specifications over the extranet so that nearly anyone with a fabricator could manufacture this weapon to help the war effort.

Reegar Carbine: Quarian electrical weapon that’s best at close range.

• This electrical weapon improves upon the arc pistol’s design by generating a sustained current on its target. This weapon is named for the quarian Reegar family, whose marines have served valiantly against the geth.

Harrier Assault Rifle: Full-auto Cerberus rifle with low recoil and heat generation.

• These Cerberus-modified Mattock rifles are fully automatic. Cerberus gunsmiths reined in the recoil issues, resulting in a gun that stays on target but delivers slightly less punch per round than a standard Mattock. As such, the weapon is typically utilized by Cerberus’s elite troops who train constantly to make every burst count.

Geth SMG: Fully-automatic geth submachine gun. Its rate of fire increases when the trigger is held.

• This submachine gun works on the same principles as the Spitfire: it shoots superconducting toroids that break apart on impact, retaining an electrical charge that flash-converts the shrapnel into plasma. Unlike the Spitfire, however, this smaller geth weapon has been modified to take thermal clips. Holding down the trigger speeds up its rate of fire, rapidly depleting the gun’s heat sink in exchange for nearly continuous fire.

Blood Pack Punisher SMG: Submachine gun with a secondary barrel that fires armor-piercing rounds.

• The Punisher features a secondary barrel that fires one armor-piercing round per main-barrel burst. It was developed by Blood Pack gunsmiths who found that their vorcha recruits frequently forgot to optimize ammo loads in the heat of combat. This configuration makes the process automatic and highly effective at penetrating armor.

Adas Anti-Synthetic Assault Rifle: Electrical weapon that’s effective against shields and synthetic targets.

• Named in memory of the quarians killed in the Morning War on the planet Adas, this weapon’s electrical attack has been optimized for medium- to long-range firefights. Alliance marines take issue with calling it a “rifle” since, technically, it has no rifling in its barrel. The quarians shrug this off, as quarian weapon terminology rarely translates flawlessly into human languages.
