Is it worth it to dual wield submachine guns?
Solution 1:
I've had some really good gameplay in confined spaces where you can spray and pray. I use scavenger pro, steady aim pro, marathon pro with radar equipment and it usually works pretty well. They are pretty worthless for medium to far range, so that's why people probably don't use them.
Solution 2:
The skorpion sub machine is a great choice for dual wield because of its high damage rate at close quarters.
I usually run a class with Lightweight, Steady Aim and Marathon. I also carry a tomahawk for quick kills when my guns run out of bullets.
