This is an old game. In the game, you play as two characters, Lucas and John. Lucas will be pushed off the roof by a female ghost and die from the fall. John will merge with a cicada, turning into a half-cicada person. When transformed into a half-cicada person, you must avoid the sun and aliens within 60 seconds (the cicada's shockwave will repel monsters), otherwise the game will fail. Finally, here's an introduction: the story has two endings. One ending is to follow the neighbor and leave the town, which is a very happy ending (choosing this ending, when starting a new game, you will have infinite bullets). The other ending is to follow the wife, where two large worms are on the bed, which is a very disgusting ending (choosing this ending, in a new game, the aliens will have increased health, making the game harder).
Actually, there's a ferry guide that provides an introduction and tells you how to proceed. Game cheats "In the Void" download by resolution
