An area of denial Kamehameha wave style beamu.
Similar to a Mass Driver, you'd anchor yourself down to a spot and power up a beam which would heat up and fire over a few seconds down range which would leave you stuck in one spot for a moment while firing out this beam and then a cool down/tear down your anchors and you're free to move again.
Would probably want a cool down on refire and disable a units "eye glow" when prepping to make the shot making it a long range weapon.
