Blue nodes are infinite resource nodes. They are really helpful, and the enemies here (big fire snake things) aren’t that difficult to deal with, especially if they go straight towards the Aegis because it will take them out with one Cannon blast. It is very helpful to have the Aegis equipped with a drill and at least one scoop (multiple drills are unnecessary, but multiple scoops aren’t bad. Turrets aren’t great anyway). The Aegis makes an amazing miner. Unlike all the other nodes, the Blue nodes never run out of resources.
