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.
