How to get the Mira achievement in World of Horror

The special super secret ending isn't connected to the investigation of the mysteries, so you should be able to find it during any run. You need to have the Blue Gem in your inventory. If you don't know where to find it, just scroll further down where we show you the exact location.

If you have the Gem already in your inventory, then you can make progress by going to the Seaside and investigating there. You'll need to keep investigating the Seaside until you get event #40, the 'Lighthouse rumor'.

Getting this one and the following events is a big combination of strategy and luck. Some of you will probably get this event in the first couple of tries, while I had to debate my own demonic possession in the hopes of finally seeing it.

Now you're going to the exact same thing in the School. Keep investigating and try to stay alive until you reach event #56, 'Empty Corridor (or is it?)'. That face clearly says it isn't, so I wouldn't venture down there.

The final location is the Forest where you'll once again keep investigating until a particular event happens. This time be on the lookout for event #57, 'Strange Lights'.

Now this event is the real deal—the Blue Gem is reacting, and you're enveloped in a stream of light before being lifted into the air and kidnapped by dogs? Aliens? Dog aliens? Whichever the answer, don't let their friendly faces fool you, because the end screen states you have perished after being kidnapped by aliens.

Where to find the Blue Gem in World of Horror

First, you need to go Downtown (1) to the Shop (2). And yes, that is a dog selling items.

While there, you can buy one randomized discounted item from the bottom of the available items list. If you're lucky, this will be the Blue Gem that will help you solve the Mira achievement.
