A new Deadlock character called The Doorman can create two interconnected doors on basically any flat wall on a map and then use them to teleport. You enter one door and exit out the other. And if the concept reminds you of another Valve classic, you're not alone.
The very Portal-esque character was added to Deadlock late last night as part of Valve's promise to gradually introduce six new heroes over the next two weeks or so.
