Board Game Geek Avg Player Rating: 8.45. This epic monster pack is designed for 1 to 6 players and was published in 2018. It's the Kickstarter Edition of the Insidious Epic Monster for Deep Madness by Diemension Games. It includes the Insidious expansion, but you'll need the Deep Madness core game (sold separately) to play. Note that paid add - ons from the Kickstarter Campaign are not included unless stated otherwise.
Insidious is a terrifying monster. It lays eggs in dark, hidden spots everywhere. When investigators face Insidious, they might win at first. But once it 'dies', one of its eggs hatches, and it comes back fully grown, ready to kill and breed. As long as an egg remains on the board, Insidious won't truly die. Can you destroy all its eggs before your team is wiped out?
What's inside?
- 1 Insidious monster miniature
- 6 Egg miniatures
- 1 Monster Card in five languages
- 2 Spawn Cards in five languages
