Camp 3 was a mining camp on the planet Sisuphos. For a while it was under the control of the Gruber brothers before the younger brother, Hans, left to take up control of Camp 4, leaving his older brother, Joseph, in control of Camp 3. Joseph himself was killed in an Open Cast Mining Tractor duel with Hans, due to the discovery of a prime lode between the two camps. The destruction of both camps' OCMTs (Joseph stole Camp 4's orange OCMT, while Hans stole Camp 3's blue one) destroyed the lode.
