Collectors are abundant and easy to find; they will mine asteroids until their cargo hold is full, and after a while they will head back to their hive queen. There are four known types of collectors, and here they are.
Note: In these pictures they are mining, the beams from them are their mining beams.
This is an Orun class collector. It is considered the easiest of the collectors class of hive bots. It has one gun that has a slow refire rate, has poor dodging abilities, and low armor.
Provides 5 XP.
Kannik Collectors
This is a Kannik class collector. It has slightly better dodging abilities than an Orun collector. Also, it fires two more powerful rounds at once.
Provides 10 XP.
Dentek Collectors
Here we have a Dentek class collector. The armor is much greater than an Orun or a Kannik, it's weapons are stronger, but the dodging abilities aren't much better. It also has the equivalent of a large port, which allows it to mount a superior mining beam.
Provides 20 XP.
Artemis Collectors
An Artemis class collector is the most dangerous of the collector class of hive bots. It will fire its guns constantly until it runs out of energy, then it will fire much less frequently, but more frequently than the other collectors.
