According to the latest whispers, the Skitarri will be getting a ranged weapon called an Arc Gun, that has a good strength to take down infantry and light mech, but is also a Haywire weapon. Great weapon with huge versatility.
Please remember that these are rumors. Very early rumors at their best. I would imagine a gun like this would be rather short range, but who knows at this point.
