Mission: Starbase Fleet Defense/Walkthrough

Stage 1: Protect the Freighters
This stage is fairly easy, simply protect the freighters. When the freighters reach a predesignated point it will trigger the enemy NPCs to enter the map. Immediately attack the enemy NPCs. As the first wave is destroyed a second wave will spawn. Destroy the second wave and the freighters will warp away. Move to the next main starbase hub and repeat until all four are saved. (Hubs: Industrial Fabricator, Transwarp Conduit, Shipyard, Comm Array)

Stage 2: Protect the Starbase
Once the final group of freighters has left the map stage 2 will begin. You will have about 20 seconds to heal or prepare yourself. When stage 2 begins, enemy NPCs will spawn in between the 4 hubs and the starbase. Be careful not to stick too close to the starbase at the center of the map. Instead you will want to be positioned as close to the spawn points of the NPCs as possible. The reason for this is so that you have as much time as you can get to attack the enemy NPCs before they start attacking the starbase in the middle of the map. Once all the spawns are destroyed this will activate stage 3.

(NOTE: It is possible to heal the starbase in the middle of the map. If the starbase is taking large amounts of damage you will need to heal it. Once the starbase's structural integrity is down to 0 you will no longer be able to heal the starbase.)

Stage 3: Protect the Hubs
After the final NPCs are destroyed during stage 2 you will about another 20 seconds to return to your original hub. (The one in which you protected the freighter groups in stage 1.) When the NPCs spawn this will begin stage 3. As the NPCs spawn they will come in large groups. Each group will have a battleship with them. The battleships should be immediately targeted and destroyed first. Do not worry about any other enemy NPC until the battleship has been destroyed. Once the battleship is destroyed turn your attention to the remaining ships until the second wave spawns. At this point, again, target only the battleship. Once the second battleship is destroyed clean up the remaining NPCs. Once your hub is cleared of NPCs move onto the next hub. Once all 4 hubs are cleared the final stage will begin.

Stage 4: Protect the Starbase Part 2
As the final stage starts enemy NPCs will spawn at the same points as in Stage 2. However this time the dreadnoughts will spawn. The goal is to again, protect the starbase. You should start by eliminating the weaker NPCs first. Once the weaker ships are either all destroyed or severely reduced in numbers everyone should focus their attacks onto the siege dreadnought. You must destroy the 4 siege dreadnoughts as quickly as possible. Once the siege dreadnoughts are destroyed turn your attention the 4 remaining dreadnoughts and destroy them as quickly as possible. Upon the destruction of the final ship in this stage the fleet action is complete and you can collect your fleet marks.

(NOTE: It is possible to heal the starbase in the middle of the map. If the starbase is taking large amounts of damage you will need to heal it. Once the starbase's structural integrity is down to 0 you will no longer be able to heal the starbase.)
