Rumor has it the new edition of the well-known tactical first-person shooter video game Rainbox Six will include an unexpected plot twist: morality. The blog Kotaku reports that:

At the heart of the game is a branching morality system that changes the outcome of key moments in the game based on the in-the-moment decisions the player makes. Early development currently has the outcome of these decisions shape the path you take toward the game’s ending, with many of the levels having multiple endings. These decisions, we’re told, can drastically change the story. In practice, that means that it will be impossible to play every level in the game on a single play-through. Instead, gamers will be rewarded with new experiences based on the changing decisions they make in subsequent plays of the game.

Head over to Kotaku for some specific instances of how this will play out.
