sentences:  Hocking had previously been a level developer on the stealth game "Tom Clancy's Splinter Cell" where he had fought to try to have the gameplay mechanics allow the player to react to being detected on a mission (such as subduing the enemy that found them), but the leaders on the team did not want to implement this, and instead on detection immediately ended the game to have the player retry.For "Far Cry 2", Hocking wants a less-penalizing system for the case when the player fails, and came upon this system, as it gave the player opportunities to make mistakes and recover from those, but still introduced risks if the player was not careful about how they found in battle.A pre-alpha video of the game, showcasing the visuals and 13 minutes of gameplay with developer commentary, was presented in Leipzig in August 2007.
