He was born in Chernarus and lived with his family in the South Zagoria province. Before the outbreak, he was running away from the law after being framed and accused of murdering his family. When the outbreak started, he was lonely and lost all his friends to the disease and has lasted many months alone. He had gained much experience and he was practically made for this new environment. He had learned many skills before the outbreak, and those skills come in handy this present day. Yet none of it aided in curing his loneliness. Every day he thought about his loved ones that he lost and wished that he can turn back the clock or even wished that he took their place so that they would still be alive today. One day, for the first time ever, he ran into other survivors who were under attack by zombies. He manages to help them in defeating the threat, but its too late, they were bitten. Although there's not much he can do, now that he knows that he's no longer the only survivor and thinks that there are probably more out there. For once in his life, he's not alone. His quest to find others leads him to a group called the Black Army, who he shares the same perspective and ideology that South Zagoria should be controlled by the people/population and not by a government or a set of laws in which had failed him and his family in the past. Now, Boris has joined this group and seeks to make a change, all in continuing his quest to find and save others.
