After an attack, you have a screen pop up, either saying "You successfully defended your yard" or "Monsters repelled", based on whether your yard was much damaged or not. After that, if you successfully defended, you will see the tribe's name, and they all say different things, kozu: "Our source of power's a secret.", leggionaire: "We're just getting warmed up!", Dreadnuat: "Science will prevail!", Abnakki: "We'll be back for your bones!", Moloch: "You'll never survive down here!". If you only repelled the monsters, another screen will pop up, saying "Damn those wild monsters!" And then you can start repairing, or instantly repair with shiny.
