This R'wkau (can be spelt "rakau" for ease for the human tongue) mercenary is not one that likes boring moments like this, waiting for the contact with the details of the task to show up.
As far as he knows this will be just the right job for him, with his shoulder-counterweighted shredder he is strong enough to use with a one-handed grip while running using his other three limbs in a well-trained almost-quaduped fashion. His shield generator gives him decent protection while he does his direct but planned and surprisingly fast assault, the style he and many of his kind likes.
