Month-End Basic Galaxy open for signupPosted on 17.01.2015

As has been practised for a while now, beginner galaxies for rank 0 and 1 players are open every Friday. Starting this year however, we will be running a special edition of the beginner galaxies at the end of each month, where up to rank 2 players will be eligible to join these galaxies as well. Join now!

It'll be sort of a champions galaxy, where you might expect to meet other players who have already possibly won an unranked galaxy. Will you forge strong alliances with them? Or wage war against them and take the spoils of victory?

Note that this is a basic galaxy, and certain technologies such as doctrines and wormholes are disabled.

Sign up if you feel like you're up for the challenge. The galaxy starts on Friday, January 30th.

Open Team Galaxy (Sign up by 16 Jan)Posted on 14.01.2015

Reminder: Players in this month's team galaxy have been assigned to their respective teams. Private team forums are now open for you to discuss tactics and strategy with your teammates. Note that there will not be a second reshuffle after teams are formed, so your HQ/Civ traits will be permanently set once you confirm them.

Galaxy 280Posted on 31.12.2014

Galaxy 280 has just been extended for another 200 turns after consultation with the players in the galaxy. It will now end at turn 500.

Participating in unranked galaxies earn you fame, which allows you to join more competitive galaxies later.

These galaxies are designed to be a place where you can test your strategy against other players who are still learning the game as well.

[CS] Advisors that appear in the galaxy are there to help new players with questions about the game, and will not participate actively in the galaxy. Feel free to contact them. You may also visit the live chat or post in the forums if you have further questions.

Unranked galaxies open every Friday.

Infinite Space GalaxyPosted on 24.12.2014

The first galaxy for the year 2015 is now open for signup! Introducing the Infinite Space Galaxy, where the concept is to have every planet have 1000 space, but with very low planet commodities. The idea is that players can build lots of buildings with all that space, and with a low research modifier to enable more of that.

Sized for 50 or more planets a player, this galaxy runs on 3 hour turns, and has no artificial end-turn set. So be prepared to choose your empire's strategy carefully in order to reign supreme in this galaxy. Do you try to hold it out and fill your planets as much as possible before war comes knocking? Or do you send your ships out early and bring war to other empires?

IMPORTANT NOTE: This galaxy was reshuffled around December 27th. Do make sure that your initial ship orders and civilization traits are reissued before ticks start on Friday, January 2nd.

To join ranked galaxies, you need to gain at least a total of 15 fame points (i.e. at least rank 1). Unranked galaxies open every Friday (unless otherwise stated).

Heavens Or Hell GalaxyPosted on 03.12.2014

After centuries of preparation, the forces of Hell have broken free and begun a rampage across the galaxies of mortals. Heaven has long ago sunk into complacency and is unable to counter the attack. Both sides are recruiting mortal allies with promises of paradise or eternal gratification. Neutrality for mortals is not possible, you must choose a faction. Will you support the darkness or the light?

As the very special time of Christmas and New Year is approaching, and the God's sun is about to be resurrected in the skies, Cosmic Supremacy is offering you to participate in a truly astrologically-themed galaxy - Heavens or Hell.

The main idea is for players to choose coat-of-arms for themselves, based on heavenly or hellish creatures that fight for honor to reside in either the top or bottom of the galaxy. Take part in shaping the galaxy's destiny and help to determine who will win the Universe - God or Devil, Good or Evil.

While this is not a team galaxy, perhaps you will find good allies that are the same kind (Heavenly or Hellish) as you. Treasons and weird alliances shall not be excluded, but nevertheless, it is your matter of honor to make sure the ultimate victory is yours.

IMPORTANT NOTE: At the request of the player who suggested the galaxy, this galaxy has been postponed a week so more players can sign up. The galaxy starts ticks on Friday, December 19th.

Juicy RL GalaxyPosted on 24.11.2014

For people having to juggle their Cosmic Supremacy (CS) cravings and real-life (RL) commitments, we bring you again a galaxy with 4-hour turns, starting this Saturday, November 29th. The long-hour turns allow you plenty of time to settle things in real life before having to check how your empire is doing.

To speed things up however, you will be given 14 colony ships to start, and juicy HQ planets with whopping 90 stats across the board. Technology modifiers are also insanely low, so expect battleships to be possibly zooming around the galaxy before the first week of real-time is even up.

The galaxy has also been fixed to have a set end turn at turn 300 (i.e. approx. mid Jan), and turns are processed at the same time as the Deterministic Galaxy. Enter now!

To join ranked galaxies, you need to gain at least a total of 15 fame points (i.e. at least rank 1). Unranked galaxies open every Friday.

Role-play Galaxy : Master of Orion's Psilon fighting for supremacyPosted on 09.11.2014

A free-for-all galaxy has been created to start on Friday, November 14th.

But there's a twist this time! There is backstory to this galaxy, where different factions of Psilons (of Master of Orion fame) have arrived at this galaxy, and are trying to gain supremacy in this sector.

To fully appreciate and participate in this galaxy, you are strongly encouraged to role-play as a leader from the Psilon race, name suggestions here, or as a scientist out to conquer the galaxy.

Keeping to tradition, with the Psilons being exceptionally well-versed in research, the galaxy will have a super cheap tech multiplier, and a high science HQ to start. But planet stats are average at best, so you'll also need to manage your economy well if you want to build those battleships or cloaked frigate fleets.

So if you feel you're up to the task, Enter now!

Speed Galaxy 8 Nov 2014Posted on 06.11.2014

A Speed galaxy is opening this weekend on Saturday, November 8th 2014. The galaxy is scheduled to start at 7pm Central EU time, equivalent to 1pm Eastern US time, lasting approximately 4 hours and completed in one sitting.

It will feature 135 turns in total, with the first 30 turns ticking at 1-minute each, while the remaining 105 turns at 2-minute intervals. There will be a scheduled 10-minute break at turn 75 at 9pm CET.

The galaxy is set up to be a fast-paced affair, with 25 population and 10 military to start, and a low technology multiplier. Planets are more juicy than usual as well.

It is open to ALL ranks, so feel free to join if you feel up to trying your hand at a speed galaxy this weekend.

Reminder: The galaxy starts ticks on Saturday, November 8th at 19:00 CET. Enter now!
