Well of course. You all know those big and fat aliens with the staves that blast you down with homing light shot thingys? Well here's a quick way to defeat them as Kurt. Go into sniper mode and aim at the center of their belt. It will occasionally open and reveal the Bif's eye. (Yes its eye is on its belt) Just fire away until you can hit the eye. (It's better to be out of the Bif's sight and try to hit it on one shot. That way you don't have to strafe around)
