I'm trying to understand the key differences between 'Versus' and 'Realism Versus' competitive game modes in Left 4 Dead 2. Could you explain how their rules and scoring differ, what makes 'Realism Versus' harder for Survivors, and what's required to play 'Realism Versus'?
Navigate to the 'Gameplay Modes' page on the Left 4 Dead Wiki. Locate and read the 'Versus' section to understand its objectives and scoring in Left 4 Dead 2. Locate and read the 'Realism Versus' section to identify its unique rules, how it differs from 'Versus' for Survivors, its origin, and any specific DLC requirements. Synthesize the gathered information to explain the differences and requirements for both game modes.
State that 'Versus' is a competitive mode where two teams alternate playing as Survivors and Infected, and that in Left 4 Dead 2, Survivors earn points based solely on progression and reaching the safe room. Explain that 'Realism Versus' combines 'Versus' rules with 'Realism' rules, making it harder for Survivors. List specific 'Realism' rules applied in 'Realism Versus': lack of Survivor glows and instant Witch kills. Mention that 'Realism Versus' originated as a 'Mutation' and became a permanent game mode due to community feedback. State that 'The Passing' DLC is required to play 'Realism Versus'.
