If you could Import any weapon from any other game and use have it in ME3 what would it be? One rule: No WMD's. Everything else is a fair game.
I go first. It'd make Infiltrator playthrough hell of a fun ordeal.

Hmmmm. good question.
I have a couple.
1. The Farsight (sniper rifle) from Perfect Dark.
Although Javelin + penetration mods is basically a substitute, minus the Farsight's auto-tracking ability. The Farsight would absolutely break multiplayer, especially for Infiltrators.
2. The Needler (SMG) from the Halo series. Not always the greatest gun, but I always found it fun to use.
3. Laptop gun (Assault Rifle) from Perfect Dark
Because turning it into a turret is so much fun.
4. DK Pistol (Pistol) from Just Cause 3
Because sometimes you want to lighten the mood or suck at headshots.
Honorable mentions:
1. Lancer (Assault Rifle) from Gears of War.
Because you can chainsaw enemies in half.
2. The following Mass Effect 2 weapons: Shuriken, Tempest, Locust, Viper.
Seriously, they suck in Mass Effect 3. The ME3 Viper has some redeeming qualities but is usually outclassed by a lot of other weapons.
