Now you’re scheming with portals!

Thanks to a partnership with Aperture Science, it’s now possible to connect far-flung areas of your Lair together using portals! These highly advanced gateways have proven to be completely safe, and provide a useful shortcut for anyone sent through them. In addition there is an exciting and completely new addition to Lairs everywhere: the autonomous Turret, which will open fire on unwanted visitors and defectors alike!

Whether you are a malevolent artificial intelligence or merely a horrible person, you can really put intruders and minions to the test with this pack – various trap prototypes and apparatus provide for ample enrichment activities (encouraged with the promise of cake). There will be fun, learning, and serious injury. For science.

Included in the FREE Portal Pack:
- New room type (Test Chamber)
- 4 new traps (Propulsion Gel, Repulsion Gel, Cake That Is A Lie, Aperture Science Multi-Purpose Science Panel)
- 4 new Loot items (Orange Portal, Blue Portal, Companion Cube, Actual Cake)
- 3 new Lair items (Turret, Security Camera, Test Chamber Door)
- New Decor items
- Accompanying Side Story Objectives
