Thumpers

Thumpers are the main mode of resource harvesting. Thumper come in 3 types, Stock, Improved, and Advanced. Each has a different capacity and HP, along with a skill level. The higher skill level, the harder it is to defend it from enemy spawns.
Thumper work in conjuncture with Scan Hammers, and are generally placed on areas of a high concentration of Crystite. When a Thumper is dropped, it is brought by aircraft, and instantly starts working. When full, or any time before hand, you may interact with the Thumper, sending it back up and granting you resources depending on skill level, capacity, and location.
If a Thumper is destroyed, all harvested Crystite is lost.
