A Era Escritório consiste nos levels 46-57, segue roteiro em caso de dúvidas:
CHAPTER 4 - OFFICE ERA 46 BELL right (Must get Balding man, not Ghostbuster) >> THROW x2 left to top >> BELL right >> TV right 47 POSSESS right to left >> POSSESS bottom to left >> POSSESS bottom to right 48 HELLHOUND Woman in top to bottom >> LAMP x2 bottom (NOT the filing cabinet) >> BELL center >> THROW center to bottom >> THROW bottom to center 49 THROW bottom to top >> THROW top to bottom >> HELLHOUND right to bottom >> LAMP bottom >> BELL top >> LAMP top 50 THROW left to right >> THROW top to bottom >> THROW right to bottom >> THROW right to left >> THROW left to center >> THROW x2 bottom to top 51 HELLHOUND Priest right to left >> LAMP x2 left (use chairs NOT desks) >> THROW left to right >> POSSESS top to right 52 THROW right to left >> LAMP right >> GHOST left >> VOID bottom 53 LAMP right >> GHOST right >> VOID top >> THROW bottom to left >> BELL left >> TV left 54 LAMP left >> BELL x2 left >> HELLHOUND Gypsy left to top-right >> GHOST left >> LAMP top-right >> TV left 55 GHOST bottom >> THROW bottom to left >> THROW left to middle >> BELL x2 center >> TV center 56 NOTE: The goal with the beginning uses of BELL is to get the Ghostbuster and Balding Man to the left and the Witch and Gypsy to the bottom. If they don't agree to that pattern, pause and retry. Also note the lowest-left room (containing the glitch object) is not used in solving the level (Thanks again Wilkz13!). BELL left >> BELL bottom >> Bell left >> BELL bottom >> VOID left >> POSSESS bottom to right >> GHOST right 57 THROW x2 left to center >> VOID top >> LAMP right >> POSSESS left to right
