Info about Left 4 Dead 2:

Official game description:
Set in the zombie apocalypse, Left 4 Dead 2 (L4D2) is the highly anticipated sequel to the award-winning Left 4 Dead, the #1 co-op game of 2008. This co-operative action horror FPS takes you and your friends through the cities, swamps and cemeteries of the Deep South, from Savannah to New Orleans across five expansive campaigns.  
You'll play as one of four new survivors armed with a wide and devastating array of classic and upgraded weapons. In addition to firearms, you'll also get a chance to take out some aggression on infected with a variety of carnage-creating melee weapons, from chainsaws to axes and even the deadly frying pan. You'll be putting these weapons to the test against (or playing as in Versus) three horrific and formidable new Special Infected. You'll also encounter five new “uncommon” common infected, including the terrifying Mudmen.  
Helping to take L4D's frantic, action-packed gameplay to the next level is AI Director 2.0. This improved Director has the ability to procedurally change the weather you'll fight through and the pathways you'll take, in addition to tailoring the enemy population, effects, and sounds to match your performance. L4D2 promises a satisfying and uniquely challenging experience every time the game is played, custom-fitted to your style of play.  
*   Next generation co-op action gaming from the makers of Half-Life, Portal, Team Fortress and Counter-Strike.  
*   Over 20 new weapons & items headlined by over 10 melee weapons – axe, chainsaw, frying pan, baseball bat – allow you to get up close with the zombies  
*   New survivors. New Story. New dialogue.  
*   Five expansive campaigns for co-operative, Versus and Survival game modes.  
*   An all new multiplayer mode.  
*   Uncommon common infected. Each of the five new campaigns contains at least one new “uncommon common” zombies which are exclusive to that campaign.  
*   AI Director 2.0: Advanced technology dubbed “The AI Director” drove L4D's unique gameplay – customizing enemy population, effects, and music, based upon the players’ performance. L4D 2 features “The AI Director 2.0” which expands the Director’s ability to customize level layout, world objects, weather, and lighting to reflect different times of day.  
*   Stats, rankings, and awards system drives collaborative play

Feature scans:
- MTX: score 5; verdict: Fair Monetization; summary: Left 4 Dead 2 is a classic co-op shooter with no microtransactions, loot boxes, battle passes, or pay-to-win mechanics. All reviews indicate fair monetization: the base game offers full content, and any DLC is traditional expansion packs. Players consistently praise the game's value and lack of predatory monetization.
- Mods: score 10; verdict: Enhanced by Mods; summary: Extensive user feedback praises mods for vastly expanding replayability, adding new content, and keeping the community active. However, there is no consensus that the vanilla game is broken or requires mods to function. Complaints about mods are rare and relate to mod safety or Workshop usability, not to base game stability. The game is fully playable without mods, which are treated as enhancements rather than mandatory fixes.
- Wiki: score 10; verdict: The Tourist; summary: The primary complaints are game-breaking bugs (alt-tab and startup crashes) and a moderate need to consult guides for navigation and achievements. No evidence of farming, inventory, or complex system dependency.
- Proton/Linux: score 65; verdict: Tinkering Required; summary: Left 4 Dead 2 on Linux is a mixed experience: the native port is widely regarded as broken, while Proton can offer better performance with required launch options (e.g., -vulkan) and community patches. However, multiplayer restrictions and persistent visual bugs prevent it from being a seamless experience. Valve's recent updates have addressed some issues, but significant tinkering remains necessary for most users.
- Steam Deck: score 60; verdict: Tinkering Required - Frequent Crashes; summary: Left 4 Dead 2 on Steam Deck is playable but requires significant tinkering. The native Linux version is notoriously unstable, forcing users to switch to Proton. Frequent crashes, mod instabilities, and multiplayer server issues are common, though performance is good once configured. Controller gyro problems add minor friction.

- Hardware Profile:
  - Summary: The game performs well across the reported Windows hardware tiers, with high FPS and stability, though some high-end configurations experience crashes.
  - Sample size: 1802 (2% coverage)
  - Audience skew: Review sample is mostly Windows-based.
  - Windows <8GB VRAM / <16GB RAM (positive, 1050 reports): Most users report good performance even on low-end hardware, with stable high FPS, though a few experience crashes or lag.
  - Windows <8GB VRAM / 16-31GB RAM (positive, 273 reports): Players generally report excellent performance and high FPS, with only occasional crashes.
  - Windows 8-11GB VRAM / 16-31GB RAM (positive, 110 reports): Game runs very well with high FPS and fast loading; isolated crash reports are rare.
  - Windows 12-15GB VRAM / 16-31GB RAM (positive, 109 reports): Performance is excellent, with high FPS even at 4K max settings, befitting the older Source engine.
  - Windows 16GB+ VRAM (positive, 43 reports): Game runs great and is well optimized.
  - Windows 12-15GB VRAM / 32GB+ RAM (mixed, 40 reports): Some users report flawless performance, while others experience critical crashes that reset the system.
  - Caveats: 1802 of 86516 reviews expose hardware metadata.; Review sample is mostly Windows-based.
Feature extractions:
- Community Price:
  - Community fair range: $5.00 - $10.00
  - Reasoning: Multiple reviews indicate that the $10 base price is considered excellent value and even underpriced by some, while others suggest the full price is slightly high for an aging game and recommend waiting for sales as low as $1-2. This divergence points to a community consensus that a fair base price lies between $5 and $10, where the game is seen as a bargain without being too cheap or overpriced.
- Playtime Metrics:
  - Game completion: N/A
  - Story completion: 10.0h
  - Session length: 1.0h
  - Endgame: N/A
  - Reasoning: The Turkish review explicitly states ~10 hours to complete all official maps, which corresponds to story/campaign completion. Multiple reviews indicate each campaign session is about 1 hour, supporting session length. The 9-hour quote is a player's personal early experience, not a typical completion metric. No reliable evidence for total game completion (including all modes and challenges) or endgame hours; those fields are set to null.

- Disappointment (weight 0.19): Reviewers are disappointed by the loss of the original's dark atmosphere and introduction of jokes, outdated graphics, and lack of originality.
