After meeting a dead end in my first play, finally I finished this campaign. Many areas are very dark so flashlight doesn't help much. Map 1 is dark & dangerous in the beginning, because in my play, there's a tank coming when we still only had a pistol. Fortunately, the location was good for "playing" with a tank, so I moved in circle in the corridors & ran when I had a chance to find some weapons to fight. All maps are about finding keys & path, so it needs a good memory to memorize the paths & where the locked doors are. Map 2 is dangerous when survivors start to climb a hill. One attack from a charger can throw some survivors down the hill and cause instant death, while the charged survivor will also be brought down to the hill with the suicide attack. . For me, map 3 is the most complicated one. My usual trick to solve wide & explorable map by walking near the border of the map doesn't work here, because the hidden path is not at the border of the map, but near the border of the map. I'll give a clue to make it easier to find: look for the path closer to the river, & then look around & look up. The path is very narrow, cloaked by the mist. . Map 5 made my eyes hurt for a moment, because the view of certain areas kept changing in few seconds of interval. The difficult part is when survivors arrive at the areas with high technology & many monitors. I had no idea about the use of the monitors, as I think they just provided some stories. The real objectives are to find ID cards to open doors & elevator. . The finale is the trickiest. Players need to think & have a courage to take a path, as the areas on the finale are mostly white or very bright so some paths blend into the white colour. The other reason is because some paths are hidden until players move few meters near the hidden paths. The only drawback on this finale is no special infected, witch or tank at all. So, the main objective of the survivors is only to find the paths to the teleporter. Pay attention to the notifications as they can help figure out where to go next. . In short, this campaign is not a linear one where players only need to follow single path to the saferoom. All maps are fully explorable, & can make players get lost easily. The lack of direction adds the difficulty, as few instructions only appear after players find the keys, & the pathfinding is fully up to the players or in other words, there's no guide arrow. Some house symbols exist, but not many & only on some maps. For the supplies, they're mostly scattered around the maps. Some saferooms have supplies, but the rest of them don't. But that gives more fun as survivors don't have a choice but to explore the maps thoroughly to find the desired supplies. This campaign is still easier than the other old Silent Hill campaign with 12 maps in total, with Leafo as the author too, because the difficulties in this campaign are only about finding keys & finding paths. It's lucky that this campaign doesn't have a puzzle solving objective like the zodiac puzzle or collecting some parts to turn on a machine or generator. The traps are still friendly, but some are jumpscare trap, but in slow motion so players still have some time to think of where to retreat when a tank suddenly appears. It's good to play with friends, but it's more difficult to play in Singleplayer or with mostly bots as survivors, as players have to keep watching over the bots because sometimes they walk really far behind if players keep running in wide areas. It's worth to keep in addons folder as it provides different sensations in playing L4D2. An old but gold campaign.
