I really need a few more longshots and bloodthirsty medals with the type, any tips?
For the bloodthirsty, play a bit safer than usual. Pay attention to the minimap to see where the enemies are and dont run out into an open area if they're watching.
For longshots, try counter sniping, such as killing people in the houses from across the way on raid.
Also does anyone else think the minigun in turbine is a person standing there when noone is using it or is it just me?
