Sift Renegade 3

Sift Renegade 3: Defiance is a game in the Sift Renegade series.

Story
The events of the game take place simultaneously to Sift Heads 4. The game starts 48 hours before Kienji's assasination, which is one of Vinnie's missions in SH4.

After Kiro and Kienji successfully reclaimed the factory taken by Triads, the latter is accepted into the Yakuza by Master Yuuma. The gang leader then gives some tasks to Kienji, which he easily fulfills. Meanwhile, Kiro is taking care of another mission assigned to him, encounters Shigeru and fights him. Shigeru, however, survives the fight.

Having arrived easier than expected, Kienji overheard the conversation he wasn't supposed to hear - it turns out that Yakuza and Triads are making a deal, which is against the former gang's law. His cover gets blown, and although he avoids getting seen, Yuuma knows perfectly who was spying on the conversation and orders Vinnie to assassinate Kienji.

What happened between Yuuma ordering an assassin and Kienji being killed by Vinnie, is explained further in Sift Renegade 3: Defiance.
