I have here ideas for modules designed for those epic-level players. These modules should come from missions, although I cannot think of what to call them. They may be used as epic-level mission tier rewards.

Reality Converter: a breakthrough in digital technology, this device can transfer computer data into mass and energy. (boosts attack and energy)

Chaos Drive Field: Harnessing improbable states of matter that eminate cross-force energy, space itself can be used to protect the ship. (boosts shield and defense)

Split-wave Xenoscope: Manipulating the properties of electromagnetism into a lens, it focuses scans while creating a shield against detection. (boosts scanning and cloaking)

verry nice and how about a modual fighter bay for the larger ships.... so you can also have an like a drone bay on your ship..... these drones can be used to boost your ship with ither attack, defence, sheilds, and can even get creative and have mining drons or ap, research ones.....that will boost the planet output for the planet you are curently orbiting wheather it yours or a legion members.....

Another kind of epic module, I was thinking of a few that look like mystical superweapons, like the Psionic Amplifyer does. These are modules that for unexplainable reasons, they work.

The iconic Tesla Coil: boosts attack and energy
Arc Caster: don't know what it will boost but it sounds cool.
Divinity Drive: boosts energy, shields, and both recharge rates

...and a few artifacts of similar nature.
Vorpal Amunition: boosts attack 20%
Spirit Caller: +1 truce for 1 week

Good one Chris....i think Carriers of some kind would be cool

Hmm, suppose I'll give a shot at suggesting a module or two...

Distress Beacon: When disabled by a player attacking you, randomly selects a member of your legion. Attacker takes damage as if they were attacked once by that person.

Emergency Breach Sealant: (possible addition to hull tech tree) Can reduce damage dealt to ship's Hull by use of minerals currently in cargo hold. Higher level varieties of Breach Sealant can use more expensive (but more effective) minerals to patch the hull

PvP Flag: increases # of players that can appear on your Battle screen, and reduces (possibly negates?) Ship's cloak for the purposes of showing up on other player's Battle screen.

Reviving this thread with a couple more ideas:

Phase Compensator: A field that alters the phase of outgoing attacks to match the phase state of enemy ships (boosts attack)

Magnetar Deflector Core: Harnessing the immense magnetic forces of magnetar to simultaneously generate power and deflector capacity. (boosts max energy and shield)

Cross-wave Absorption Dampener: Harnesses multiple states of incoming energies as system power. (boosts cloak, defense, and energy)

Just for fun, here are my own.

Dimensionally Transcendental Pod-A container that uses interdimensional technology makes it bigger on the inside. Boosts Deck, and Cargo stats.

Hyperion Power Converter- A device that draws power from the universe itself. Boosts power, and energy recharge

Reverse Meta-Chron Shield-An amazing device that absorbs energy dispelled at you by attacking ships...and reroutes at them. Increases defense, shield, and will automatically deal some damage back to enemies.

Transponder Locater- A module that searches data banks to find certain ships. Adds one NPC slot, and increases chance to find rarer NPCs.

For me, what would really make an epic module is something that allows for creation of scout size ships and they would come from an entirely new tech tree called "Mothership Technologies" for ships sized Titan and above. These modules will not occupy deck space but cargo spaces instead and they can be deployed to guard planets or help fight NPCs or help in counter attacks when the player is off line. Rank points can be spent to improve their stats such as energy,attack,defense,cloak and scan and each rank point = 20 points of crew that can be spent on them. The greatest weakness they have though is that once they're disabled they're gone for good maybe some of the crew can survive and return to your mothership.

Probably not a good idea, sounds complicated.
