Story-related and cannot be missed.

The Shadow Chamber is a facility that can be used to research several projects and allows the player to see how many aliens (and what species) are located in a mission from the Geoscape. In order to build it, you must first research Alien Encryption. The cost of the Shadow Chamber is $125 ($300 on Legend), it requires 5 power, the build time is 14 days and the monthly upkeep is $30. You can only research one project at a time so you will have to suspend any research you have going on with Dr. Tygan to begin working on the Shadow Chamber projects. You must complete all of the Shadow Chamber projects in order to unlock the final mission so you should get started on these projects as soon as possible.
