A complex is EVE's equivalent of a fantasy MMO's dungeon. Itâ€™s a pocket of space that is locked off from the outside world except for an Acceleration Gate (not to be confused with a stargate), kind of like a mission. Inside, you will either find drug runners, criminal hideouts, pirates, or rogue drones. You find complexes either with scan probes (exploration) or in certain COSMOS constellations.
For the COSMOS complexes, see the COSMOS page.
 DED complexes
Once upon a time these complexes were static beacons in certain systems, which you could warp to and enter at any time. They respawned 8 hours after being completed (usually by killing the final overseer (a special pirate NPC) or destroying some structure) and at downtime. Since a lot of the gates inside the complexes required keys (found in one of the first rooms), this lead to crazy rushes at downtime to farm keys and control when the plex respawned, as well as a lot of drama, since plexes can be hugely profitable.
A while ago however, CCP removed the static complexes. They still exist, but now you have to probe them down, and they can only be run once before despawning and moving somewhere else. While they were at it they also seem to have unlocked all the gates; the keys still drop but they aren't used anymore.
DED complexes have a difficulty rating ranging from 1 (easiest, can be run in a frigate) to 10 (hardest, requires multiple well-fit battleships). Only complexes of difficulty 6/10 and higher spawn in 0.0, the easier ones can only be found in empire. The harder the complex is, the better loot it drops (obviously).
A DED complex is easily recognized by the popup you get when you initiate warp to it; it has a message from DED with some RP bullshit about what the local pirates are doing in the plex and what the difficulty rating is. If it doesn't have a difficulty rating, it isn't a DED plex but an escalation site (some of which also give you popups when you warp to them).
 Loot from DED complexes
Besides the rat bounties you get, the complexes can also drop some extremely expensive stuff, namely deadspace modules of various grades (like faction modules but better; the better ones being on par with the best officer modules), which can be sold on Jita contracts for potentially gigantic sums of money (the best deadspace modules can be worth well over two billion ISK each) and Overseer's Personal Effects, which can be sold to NPC buy orders for instant spacebux.
Generally, 1-3/10 drops frigate-sized, 4-6/10 drops cruiser-sized and 7-10/10 drops battleship-sized modules. There are different names for these, for example the Angel frigate-sized stuff is called Gistii, the cruiser-sized Gistum and the battleship-sized Gist. Each tier has three different grades (or four grades for the battleship-sized gear), namely X (battleship-sized only), A, B and C, with X being best and C worst. X-Type stuff is generally on par with the best officer modules in the game and can (depending on what it is) be insanely expensive. What drops is (in theory) determined by the difficulty rating of the plex, as follows:
- 1/10: frigate-sized C-Type
- 2/10: frigate-sized B-Type
- 3/10: frigate-sized A-Type
- 4/10: cruiser-sized C-Type
- 5/10: cruiser-sized B-Type
- 6/10: cruiser-sized A-type
- 7/10: battleship-sized C-Type
- 8/10: battleship-sized B-Type
- 9/10: no such DED complex exists, but it would have dropped battleship-sized A-Type if it did
- 10/10: battleship-sized X-Type
However, with CCP being CCP, stuff doesn't really work out perfectly as it should in the game. Here is a handy list of all existing DED complexes and what kind of deadspace modules they actually drop (taken from this list):
- 1/10: loot table probably broken (should drop Pithii C-Type)
- 2/10: loot table probably broken (should drop Pithii B-Type)
- 4/10: loot table probably broken (should drop Pithum C-Type)
- 6/10: Pithum A-Type
- 8/10: Pith B-type
- 1/10: loot table probably broken (should drop Corelli C-type)
- 3/10: Gistii A-Type (loot table mixed up with the Angel 3/10, should drop Corelli A-Type)
- 4/10: loot table probably broken (should drop Corellum C-type)
- 10/10: Core X-Type
- 1/10: loot table probably broken (should drop Centii C-type)
- 3/10: loot table probably broken (should drop Centii A-type)
- 6/10: Centum A-Type
- 10/10: Centus X-type
- 2/10: loot table probably broken (should drop Gistii B-type)
- 3/10: Corelli A-Type (loot table mixed up with the Serpentis 3/10, should drop Gistii A-Type)
- 5/10: loot table probably broken (should drop Gistum B-type)
- 7/10: Gist C-type
- 8/10: Gist B-type
- 10/10: Gist X-type
- Blood Raiders
- 1/10: loot table probably broken (should drop Corpii C-type)
- 4/10: loot table probably broken (should drop Corpum C-type)
- 6/10: Corpum A-type
- 10/10: Corpus X-type

 Escalation complexes
Escalation complexes are the other type of complexes, added relatively recently together with exploration. Unlike the DED complexes they were never static to begin with, you've always had to probe for them. They are quite different from the DED complexes; instead of a single site there's a whole chain of sites, with the final site being the one that might drop the delicious deadspace loot. The initial and intermediate sites only rarely drop anything worthwhile; the best you can get is a faction spawn.
Once you've probed out the initial site, you will have to run it. Each site has a trigger of some kind (usually blowing up one of the rats, blowing up a certain structure, or in some cases just bumping into or approaching some object), that may or may not trigger an "escalation". An escalation means you get a temporary bookmark expiring in 24 hours (in your journal, under the "expeditions" tab) a few systems away (usually ranging between 3 and 10 jumps), where a similar complex is located. Running that and tripping whatever the escalation trigger is may or may not give you a further escalation, until you get to the final site (usually the fourth escalation), which then may (or may not) make you space rich.
 Types of escalations
Just like DED complexes, escalations vary in difficulty; the easiest ones can only be found in empire. The easiest 0.0 escalations are soloable in a T2 fit, decently skilled battleship, while the most difficult ones require either a capital ship or a very heavily tanked battleship supported by a few priests to finish.
The following sites are common to all factions and are listed in order of difficulty, easiest first (empire sites not included). The difficulty refers to the escalation chain as a whole, not just to the initial site.
- Faction base: soloable in a battleship.
- Faction fortress: difficult but possible to solo in a battleship, soloable in a Marauder, or easy with a BS plus a priest.
- Faction military complex: requires a battleship tank plus at least one priest; final site may be very difficult unless you have two or more priests.
- Faction provincial HQ: requires a heavily tanked BS as the tank, supported by 2-3 priests. Final site should be doable with that but you might want to run it with a carrier instead.
In addition to this, each faction has a few unique sites where the difficulty varies.
 Loot from escalation complexes
The loot from the escalations is roughly inline with the loot from the DED plexes, at least when it comes to deadspace modules. They do usually not drop overseer effects, although there are exceptions. Do note that only the final site in an escalation chain drops deadspace loot; the initial site usually drops nothing but the intermediate stages may drop faction modules.
The list goes something like this:
- Faction base: battleship-sized C-Type
- Faction fortress: battleship-sized A-Type
- Faction military complex: battleship-sized A-Type
- Faction provincial HQ: battleship-sized X-Type
The unique sites for each pirate faction (i.e. Domination Fleet Staging Point, Blood Raider Temple Complex etc.) are not easily predictable loot-wise, but usually it's battleship-sized deadspace gear plus some kind of overseer effects.
 Some escalation protips
- The chance to get the first escalation in the chain from the initial site seems to be around 20% for the base/fortress/military complex/provincial HQ sites, higher for the faction-unique sites. If you get it, everyone in gang that is on grid will get a popup with a description escalation; the person who triggered it is the one who gets the bookmark. For everyone else the popup will just say who got the bookmark. If you do not get the escalation, nothing will happen. This is not broken, it's just that you frequently get jack shit from the first site. Far from all sites escalate.
- On the other hand, once you've gotten the first escalation, the chance of getting the subsequent escalations seems substantially higher. Unlike at the initial site, when tripping the trigger you will (almost) always get a popup that says either "dead end" or one that gives you a further escalation. The escalation chain can deadend at any time; this is not broken.
- The warpin points for the escalations can vary slightly. For example, in some escalations there's a gate with some rats on it, and activating the gate leads to an empty or almost empty room where you have to approach some object, kill a beacon or a single frigate to get the next escalation; the thing is that this gate isn't always there, sometimes you land directly in the second room and get escalated immediately. YMMV.
- If you get an escalation but don't have time to run it before the 24 hours runs out, you can reset the timer to another 24 hours by warping to the site in a pod.
