Farming is when you repeatedly send ships to a planet for resources, ships, or rank. In the beginning you can have 5 active fleets at a time. Building up your fleet research will allow up to 10 active fleets at a time. The term "planets" is used for other player' planets, empires and pirates which are npc (non-player characters controlled by the game), asteroids, stars, debris, nebulas, and swarms. Planets are grouped in planet groups throughout the galaxy. Travel time is the same no matter where in the galaxy the planet is located so there is no need to travel far from home. Except for other players, all planets are the same so a level 2 pirate near your planet is the same as any other level 2 pirate in the galaxy. The reason for staying close to your home planet is that you do not have to screen swipe through the galaxy. I tend to find locations of the planets I want to farm or attack and then uninstall and re-install the game (after setting up your password of course). This will wipe your galaxy locations giving you a clean galaxy. I now mark the few places that I found earlier and have a nice clean screen.
Planets refresh instantly so you can farm (also know as harvest) the same place over and over again.
Rank farming is attacking empires and pirates to increase your rank. Most players do not consider this farming. Instead they call this attacking. This information can be found in the attack sections of this guide.
Ship farming is done mainly by beginning players to build up their fleet size without using critical resources. It is also a way to get ships that are more powerful than you might be able to build yet. Ship farming allows you to find abandoned fighters, corvettes, frigates, battleships, carriers, and dreadnaughts. You cannot find bombers, stealth ships, barges, or freighters.
To farm for ships, simply send a single fighter to any of the resource planets - asteroids, stars, debris, nebulas, and swarms. Since you are only sending one fighter you do not have concerned about pirate ambushes since they can only taken your one ship. There does not appear to be any benefit between the resource planets or their levels. Higher level planets appear to give out more powerful ships just as much as the lower level planets. You will find mainly fighters, corvettes, and frigates though the bigger ships are out there. Keep farming and you can build up a decent fleet.
Resource farming is what most players are doing when they say they are farming. This is a great way to increase your resources above the facility build limits. The amount of resources that you can keep on hand are theoretically unlimited though the most I am aware of is 80 billion Titanium.
Each type of planet can be farmed for a specific type of resource:
Asteroids - Titanium.
Stars - Power.
Debris - Titanium and debris.
Nebulas - Plasma.
Swarms - Nanites.
Each planet type has three levels, 1,2, and 3. There are some level 4 asteroids and stars. These were previously glitched but they appear to have been fixed. The higher the level, the more resources you can recover, but you also have a higher risk of being ambushed by pirates. If you are ambushed, it will be by pirates equal in strength to the level of the planet you are farming. Thus if farming a level 2 asteroid, you can be ambushed by a level 2 pirate. This is why you should only farm at a level that your ships can defend. Being ambushed is the same as attacking pirates. You have ship losses and will gain rank, titanium, and power.
Usually this is the place that I start rambling on about numbers and formulas. Not anymore. Hopefully i can explain the concept fo farming in terms that everyone can understand. It is not as complicated as it appears. The goal is to collect as much resources as quickly as possible. Just sending a bunch of ships will work, but it is better if you understand how the two types of ships work together. The two types are Cargo and Combat.
Barges - 4,000 cargo spaces each
Freighters - 80,000 cargo spaces each
Fighters and Interceptors - 1 cargo space each
Bombers - 2 cargo spaces each
Corvettes - 4 cargo spaces each
Frigates and cruisers - 15 cargo spaces each
Battleships - 80 cargo spaces each
Carriers - 100 cargo spaces each
Dreadnaughts - 500 cargo spaces each
You must first understand that although the cargo ships have huge cargo holds, it is the combat ships that actually haul most of the cargo. The combat ships in turn allow you to actually find the resources. After you have decided on the planet you wish to farm, send out 1 freighter or 20 barges along with combat ships equal to what you would send to attack pirates at the same level. For example, to a level 2 asteroid I sent 10 frigates, 3 carriers, and 1 freighter. My battle report shows that my cargo hold is 80,450, I found 9,221 Titanium, and I was able to bring back all of it. If I just add one more freighter, my cargo hold jumps to 160,450 but the amount of Titanium found only jumps to 9,285. If I instead send 10 more carriers instead of the 1 extra freighter, my cargo hold is increased only to 81,450, but I am able to find and bring back 23,193. This is a much better increase. At this point, I want to continue to add more combat ships until I bring back enough Titanium to fill half of my cargo stores. For me, this was with 20 Frigates, 28 Carriers, and 1 Freighter. It does not matter which combat ships you send though if you send fighters, you will have to send more since they each only have 1 cargo space and if you send Dreadnaughts, you would be sending less. The reason why I stop adding combat ships after I reach half my cargo limit is because on occasion you will get a double harvest and you want to make sure that you can carry it all. If you were to continue to add more combat ships, you would eventually find more Titanium than you can carry. For my example, when I sent 20 Frigates, 83 Carriers, and 1 Freighter, I found 95,441 Titanium but could only bring back 88,600 since that was my total cargo hold size. At this point, adding more combat ships is useless. Going back to my example, I stopped adding combat ships at 20 Frigates, 28 Carriers, and 1 Freighter. I now added 1 more Freighter. My cargo hold increased to 163,100 and I was able to find/bring back 42,420 Titanium. The process now continues as before. I increase the number of combat ships until I find and bring back half of my cargo hold. At this point, I add another Freighter and continue the process. Of course once I know the number of ships to send, I can make multiple runs with that same combination. You will bring back about 20% more resources by splitting your farming into multiple runs since as your fleet size increases, you will get less and less resources per ship added.
