《寂静岭2》攻略详解：
一、硬币谜题 该谜题在不同难度下答案不同，且越容易的难度所给提示更直接。 EASY答案：老、空、蛇、空、囚 NOMAL答案：空、老、囚、空、蛇 HARD答案：空、老、空、蛇、囚
二、三楼大门密码 EASY或NOMAL难度下直接给出密码。 HARD难度下，游戏提示较为晦涩，提供英文提示，可用九宫格表示，英文起笔和收笔位置即为密码数字。例如“Z”从1开始，转至3，再至7，最后至9，Z的答案即为1379。
三、TRICK OR TREAT 当JAMES和MARIA一同坐电梯时，会触发此事件。JAMES的收音机突然收听到问答游戏“TRICK OR TREAT”，回答三个问题后，若答对，会在三楼的STORE ROOM发现神秘箱子，获取珍贵道具。答案顺序为“01：3，02：1，03：3”。
四、无提示密码 在门旁发现密码按钮，需观察力。密码由三个数字组成，数字略变白色即为密码组合。因每次游戏密码不同，无固定答案。
五、谁人没罪 两间房间中，一间有6具尸体，另一间有6根绳子。根据故事内容，估计被诬告的人，拉下空房中的绳子即可取钥匙。不同难度答案如下： EASY：诱拐 NORMAL：纵火 HARD：伪造

十一、地下监狱吊绳谜题 难度：Hard “I do not wish to die. But tomorrow I will climb the thirteen steps. Please someone answer me, why must I die come the morning? The man imprisoned beside me believed me. 'Because they’re all insane, that’s why,' he said. Of course I know his opinion will change nothing. 'Now you know why I struck out at them,' he muttered. The man executed yesterday, the one who had said his job was to sell dreams, says that was not true. But the man to be executed the day after tomorrow for stealing children shouted back that it was true. The man hanged today did not answer. 'They’ll kill me either way,' he said. He was caught embezzling public money, so he hasn’t any hope for mercy. The man who is always quietly smiling to himself said 'I am happy for I will soon be with her.' I don’t wish to die. I long only to return home. But I know it is not to be. Though I have done nothing, this crime has been thrust upon me. Someone save me. This is not judgment. They are bloodthirsty and I am their sacrificial lamb!” 答案：无辜的是犯下counterfeiting的犯人
十二、地下监狱吊绳谜题 难度：Normal “Dead men, dead men swinging in a tree. How many dead men do you see? Tongue turned blue and face gone grey watch them as they twist and sway. The first one killed the butcher man, then cooked him in the frying pan, served him to his hungry guests, and gave them seconds on request. The next one with his smile and sweets stole poor children off the streets to men who dressed unsavory. He sold them into slavery, breaking into a home at night. The thief he had a nasty fright, filled his foolish head with ale, woke in the morning in the county jail. The artist with his daunting skill tried his hand at painting bills but caughting in rain he was undone when the ink held use did start to run with promises of great return, taking gold he did not earn, bundled it up out of sight, quietly slipped off into night. Three houses into ashes burned, the sheriff with no place to turn did spy a stranger to his town, locked him up and beat him down. Dead men, dead men swinging in a tree. How many dead men do you see? Six feet long and six men wide, round their necks the noose be tied.” 答案：无辜的是犯下arson的犯人
十三、硬币的诗解法 Hard等级 Blue Creek Apartment 105号房 硬币谜题的诗与解答 First lies the seat of He who is peerless, Silent and empty, heartless and fearless. Beside him sits one who knows, The place of the servant is next to the throne. Dozens of feet, yet not a single toe, The one that is hidden beside him doth go. Seducer of dreams, creature of Hades, Lying further from Man and closer to lady, Man and Woman seeing all, Heedless to the Raven’s call, Silent and Hidden the two may be, The be not there for you to see. Return them to whence they would be, And blessing shall descend on thee. I speak thus with the North Star behind me, The birth of the sun is the start of the story. 谜底是（空格用○表示）○、老人、○、蛇、囚犯
Normal等级 Blue Creek Apartment 105號房 硬币谜题的诗与解答 Three bright coins in five holes be, At one end sits the Seducer of she, The wind from behind the woman doth play, The formless Ones, Null, lies furthest from they.
