Professional mercenaries Kane and Lynch violently and bloodily traverse the criminal underworld of Shanghai in Dog Days, the sequel from IO Interactive, the creator of the original game.

The gameplay is similar to the first game. In the main campaign, players control one character while the computer controls the other.

While the original game, Kane & Lynch: Dead Men, followed the harrowing adventures of former death row inmates primarily from Kane's perspective, the second game is set from Lynch's perspective.

His psychopathic tendencies lead to more improvised missions and spontaneous action scenes compared to the careful strategy stemming from Kane's military background.

As the game begins, Kane travels to meet Lynch in the world's largest city, where he hides among 15 million people in Shanghai.

Separated after the events of the first game, the two criminals reunite to undertake a risky game with unimaginable profits.

• In cooperative and competitive multiplayer modes, players control both characters.
• Missions include easy platform exploration and puzzles, navigating through various large urban environments, with an emphasis on armed conflicts involving firearms of almost all sizes and types.
• The game's graphic style mimics reality shows and amateur documentaries, with shaky cameras and stories told through YouTube-style videos.
