The Sift Renegade Games are spin-off games that take you back to Kiro's history with the Yakuza. There are technically 4 games in this series but Sift Renegade 3: Defiance is a game with three missions with the intention of being an extension of Sift Renegade 3.
The games in this series are:
Sift Renegade[]
The game's events are set between Sift Heads 4 and Sift Heads 5. Kiro attempts to hunt down and kill the person responsible for his brother's death. Having found out that Kienji had been killed by Vinnie, he resolves to take vengeance on him.
Sift Renegade 2[]
After failing to kill Vinnie in Sift Heads 5, and being told that killing a paid contractor is a wrong idea, Kiro attempts to hunt down the person who paid for Kienji's death. Eventually, he joins forces with Vinnie, paving way for the Sift Heads World series.
Sift Renegade 3[]
Prequel to the previous games, which takes place at the same time as Sift Heads 4. Depending on the mission, you play as Kiro, his brother Kienji, or Vinnie. Kienji completes his assignments from the Yakuza, before discovering that Yumma was going to betray the Yakuza. As he is about to reveal the details to Shawn and Shigeru, he is assassinated by Vinnie. This assassination was previously depicted in Sift Heads 4, in a mission labeled as Shadow of Traditions.
Sift Renegade 3: Defiance[]
Kienji attempts to inform Kiro about the betrayal after rescuing Shawn and Shigeru. He is then killed by Vinnie while explaining the betrayal to his associates. Unlike the base Sift Renegade 3 game, in which Kiro, Kienji and Vinnie were playable depending on the mission, the expansion is seen only from Kienji's perspective.
