The '''Shield Scanner''', also known as '''Scanner Type II''',''Half-Life 2 Prima Guide'' is the other version of the City Scanner which appears briefly in the later chapters of ''Half-Life 2'' and at the end of ''Episode One''.  

==Application==

The Shield Scanner is commonly used by Combine forces to drop Hoppers in combat areas and is equipped with a large pincer arm which is kept concealed behind an armored plate. These mines are typically dropped in areas in which the Combine forces aim to limit the enemy's movement, such as streets and alleys, though occasionally the Scanner will attempt to drop the mine on top of the player.

When not handling mines, Shield Scanners are used for scouting and reconnaissance purposes. They also sometimes accompany Striders and act as spotters for it, searching buildings to report the positions of targets that may be hiding inside which the Strider would otherwise be unable to see. Like the City Scanner, the Shield Scanner can take pictures of targets, but with a longer lasting flash. Like the City Scanner, Shield Scanners are powered by a single battery, which can occasionally be salvaged from a destroyed unit and reused for a HEV Suit. However, it does not mirror the City Scanner tactic of attempting to crash into its attacker when critically damaged.

==Behind the scenes==
*Another early Scanner model was named "Wasteland Scanner".Playable Development of Half-Life 2 game|''Half-Life 2'' leak files

*The Scanner design was initially modeled after the shape and movement of a piranha.

*Originally, the Shield Scanner was to be protected by an energy shield and be equipped with an undetermined weapon.Development of Half-Life 2 game|''Half-Life 2'' leak source code The energy shield model, "Scanner_Shield.mdl", can be found in the playable ''Half-Life 2'' leak files, but can only be viewed in wireframe mode, as its texture does not show (it can however be found in the Shield Scanner texture folder). It appears as some sort of bell jar, surrounding the machine. This shield may explain the origin of the scanner's name. This is also confirmed in the Source SDK files.

*In its texture files, the Shield Scanner is referred to as "mine layer", likely dating from before it got its final name.

==Trivia==
*A view of the Shield Scanner in the SDK model viewer reveals animation sequences that show it slashing and attacking targets with its claw. This is never seen in-game.
*The ''Half-Life 2 Prima Guide'' states the Shield Scanner is equipped with a quick-firing machine gun. This is either a mistake by the author or a reference to a cut feature.
*In ''Half-Life 2'', the only way to create a Shield Scanner is by using an npc_scanner and prefixing the map with "d3_c17". ''Episode One'' adds a separate entity for Shield Scanners.
