The Shield Scanner, also known as Scanner Type II,[2] is the bio-mechanical counterpart of the City Scanner which appears briefly in the later chapters of Half-Life 2 and at the end of Episode One.

Application[edit]

Closed Shield Scanner.

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. Shield Scanners are also similarly powered by a single battery which can occasionally be salvaged from a destroyed unit and reused for an HEV Suit. However, it does not mirror the City Scanner tactic of attempting to crash into its attacker when critically damaged.

Behind the scenes[edit]

Originally, the Shield Scanner was to be protected by an energy shield[4][5] and be equipped with an undetermined weapon.[6] The energy shield model, "Scanner_Shield.mdl", can be found in the playable Half-Life 2 leak files, but only its shape is visible in wireframe mode as its texture does not display (it can however be found in the Shield Scanner texture folder). The shield appears as some sort of bell jar surrounding the machine, potentially explaining the origin of the scanner's name. Additionally, a quick-firing machine gun is mentioned in the Half-Life 2 Prima Guide that is not present in the final game.[2]

In its texture files, the Shield Scanner is referred to as "mine layer". 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.

In Half-Life 2, the Shield Scanner is hard coded to only be present in the City 17 levels during the Uprising. In any map with a name that uses the "d3_c17" prefix, all npc_cscanner entities, which are normally City Scanners, are forced replaced by Shield Scanners. Episode One introduces a separate entity for Shield Scanners.
