Augmented Combine

Overview
Augmented Combine (unofficial nickname) are rare, modified Combine units that sport discolored equipment, and have noticeably higher health and accuracy than their normal selves.

The frequency these units appear depends on the difficulty setting; Augmented are essentially non-existent on Easy mode, but are merely uncommon spawns on Nightmare mode.

These units are much stronger than their default counterparts. For example, a default Metrocop is only able to take one or two headshots from a CZ57 before dying, whereas an Augmented Metrocop is able to take up to five or six.

They are also generally more accurate, commonly landing headshots even while spraying with their SMGs, often making them very high threats, especially since they are able to appear in even the earliest levels; they are able to spawn as early as Point Insertion, even before the player has their HEV suit.

Augmented Combine are able to spawn with Riot Gear as well, making them even more powerful than they were before.

Almost any type of Combine can spawn as an Augmented, including Elites, and possibly even Aces.

While the accuracy values are currently unknown, when compared to their default variants, red units have roughly four times as much health, whereas blue units have a hefty eight times as much health.

Tactics
-Since Augmented Combine are often quite hard hitting and difficult to take down, it's often best to take them out as soon as possible, especially if they are armed with stronger weapons such as the OICW.

-Always try landing headshots on Augmented units. Weapons like the Karabiner should be able to make short work of them with a few shots.

-If you are particularly desperate to get rid of them as soon as possible, you can eliminate them with heavy weapons such as the Laser Rifle, although this is best saved for dire situations.

-Augmented units that spawn with Riot Gear are, as one would expect, particularly tough to take down, and are particularly threatening as a result, especially if they spawn with helmets. Explosives may be necessary to take them out quickly, such as an A35

-Despite their higher health, Augmented Metrocops will still die instantly to fire. Weapons such as the Flare Gun will make short work of them.
