Half the weapons in Mass Effect 3.
Such an incredible variety of awesome guns.
Shotguns:
First you have the Claymore for pure single shot shotgun destruction. Dat boom. Boxy, brutal and inelegant, it's shaped like a brick with a handle and a barrel.
Then there is the Reegar Carbine. My god. Imagine a flamethrower, but instead of fire, electricity. Terrible range, terrible ammo limit, melts groups of people impossible fast.
And the Crusader. I hated this weapon when i first used it, but only because i wasn't worthy of it. More of a cannon then a shotgun, really.
Sniper Rifles:
The Widow and Black Widow. Gotta love the power and being able to laugh when enemies get in cover and shoot straight through it is always fun.
Next up is the Javeline. Very hard to use well, due to the slight charge up before firing, but once you are used to it the Javeline is insanely fun to use. The ability to see through walls and an absurd degree of cover penetration make this more of a siege weapon then a rifle. And im okay with that.
Assault Rifles:
The Typhoon. Just......the Typhoon. So much dakka. It's a good thing this gun comes with a face shield, since once you start firing you will never want to stop.
The Saber. Straddling the gap between AR and SR, the Saber is brutal, accurate and sounds so very sexy.
SMG:
The Hurricane is very well named. Trying to keep it on target at full auto is completely impossible, but it deals so much damage that that rarely matters. Up close or with fire discipline, an absurdly overpowered and very satisfying gun.
Pistols:
The Supressor is an alright gun. Good damage, nice clip size, excellent rate of fire. And then you go for a head shot. The Supressor has a massive headshot multiplier, going from a good weapon to possibly the most powerful in the game so long as you can aim well. Takes skill to use, but so much fun when you can.
The Executioner is the most brutal pistol i have ever used. Massive recoil and only one shot per clip, but it does so much damage that you will be too busy laughing to care.
