Firefight Weapons Pack
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!
The Firefight Pack includes the following weapons:
Indra Sniper Rifle: Fully automatic sniper rifle.
Krysae Sniper Rifle: Heavy turian sniper rifle with explosive rounds and an automatic scope for all-range fighting.
Reegar Carbine: Quarian electrical weapon that's best at close range.
Harrier Assault Rifle: Full-auto Cerberus rifle with low recoil and heat generation.
Geth SMG: Fully-automatic geth submachine gun. Its rate of fire increases when the trigger is held.
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.
For those interested, Kotaku posted their impression of the DLC hands-on
http://kotaku.com/5931451/riding-a-mech-to-the-bottom-of-the-ocean-in-mass-effect-3s-leviathan-dlc Small part from it "According to BioWare's Nick Clifford - Leviathan will be 2 to 3 hours long, probably closer to 3 hours. Clifford said they were shooting for about a Lair of the Shadow Broker depth."

Finally!!!!!!!!!!!!!!!!!!!!!!!! some Single player DLC I mean it seems like Multiplayer has gotten alot of DLC while single player has not but I guess that could be more difficult to make single player having to do voice overs and animations and stuff like that.
