The Entrance Gate is the gate that leads into the Avengers Mansion. Stationed in front of the complex is JARVIS, the automated system that protects the entire mansion and is always prepped with everything anyone needs. You must have your ID pass to enter, and if you don't, JARVIS will make sure you do not enter. This is also where normal civilians walk by and sometimes even villains try to enter through here. There is a secret entrance to the mansion, but only some know about it.
