SuitCase

The Citizen Suitcase is a point entity that is seen in Half-Life 2. The suitcase is used by both Citizens and The G-Man.

Overview
The suitcase was only used for scripted sequences only. The suitcase can only be spawned by typing give_weapon_citizensuitcase. Once the player has the suitcase it uses the world model instead of the view model. Pressing both right and left mouse does absolutely nothing. The suitcase replaces the inventory position of the MP5K and uses its beta icon. Once spawned in you can only use that weapon, if you were to spawn in another weapon and go back to the suitcase it would remove that spawned in weapon.
