Event Snatcher takes place in the middle of the 21st century. 50 years have passed since Lucifer Alpha, a powerful bioweapon, destroyed the lion's share of the human population. In East Asia, on one of the islands, scientists discovered robots that look like humans. These androids are called Reavers, they kill people and use their skin to camouflage themselves in society and not arouse suspicion.

The city of Neo-Kobe was closed by the government to identify all criminals and destroy them. An organization called JUNKER was created, whose members hunt the Kidnappers and destroy them by any means necessary. The user will play the role of Gillian Seed, a man who suffered amnesia due to the disaster. He remembers only a small part of his own past and some moments with his ex-wife Jamie.

The main character decided to become members of the group JUNKER to try to shed light on his past. Gradually, he will become more aware of his own life and the moments that made him who he is at this moment. In the gameplay, the gamer will have to solve puzzles created in a point-and-click style. The project offers a journey through a semi-open world. Many locations are unlocked by completing quests and solving logic problems. In some segments of the passage you will have to fight with enemies located on a 3×3 grid.
