Model Dz5 security door

Captain Neg's model Dz5 security door

Model Dz5 security doors were blast doors which included an artificial intelligence with a vocoder and photoreceptor set in them, as well as an advanced laser cannon defense system. Captain Neg's front door was of this type.

The Dz5 was an upgrade of the model Dx5 security door.
