A Resource Node is a yellow dot on the MiniMap that may be harvested for Resources by building a Refinery on the node. These can vary in appearance from map to map, but are usually denoted by a steaming rock-like structure. Resource nodes can be utilised by instructing a player to move nearby, and the Commander constructing a Refinery over the node. Refineries can also be built if they are within range of any existing structures.
Tip: Harvesting multiple resource nodes at once can allow for greater progression through Research and building
Tip: Not all nodes give the same number of resource points per second; Usually those in the centre of the map will be more valuable than those at the edges.
