Infester

The Flood Infester is a flood pure form encountered on the Ark in 2559.

Description
The flood infester is a flood pure form that is encountered in the Halo Wars 2 DLC, Awakening the Nightmare. It serves as the flood's anti-vehicle unit and is relatively common on the battlefield during the Awakening the Nightmare campaign. The infester walks on four legs and has a large pulsing sack protruding from it's abdomen, which contains flood spores. It will attack the player's ground vehicle units by pouncing on top of them and exploding, releasing all of the flood spores into the vehicle and it's crew. This attack will turn the player's vehicles against them as they are converted into flood vehicles.

Tactics
Since infesters will infect and turn the player's vehicles against them, it is best to attack them with infantry or air units instead, before allowing their vehicles to move up, Elite Rangers may be the best choice due to their anti-infantry properties. Alternatively air units are hard for infesters to reach, but infesters are often accompanied by Seeder Infectors, which are the floods anti-air units.
