Latest Dev Diary (12/25/22)

Currently in a beta status, Beyond the Relays is committed to bringing you the most accurate and thorough representation of the Mass Effect universe possible Currently featuring a map designed around a fully functional Mass Relay Network, 2 different map types, and 24 empires available to play, there is a lot here for fans of Mass Effect or Stellaris to dive into and enjoy.

The Map

Designed around a fully realized Mass Relay Network, the map of BtR follows the same structure that is shown in the Mass Effect trilogy, with each star system forming part of a star cluster. These clusters are disconnected from one another via hyperlanes, leaving only Mass Relays as the primary means of traversing the galaxy. Currently including every system from Mass Effect lore, as well as many pulled from popular mods for the trilogy, fan fiction, and our own original creations, our smallest map is what has been released so far containing 400 star systems. We currently offer 2 map modes:
  • Sandbox - the traditional Stellaris game mode, start with a fledgling empire who has just reached the stars, and forge your destiny amongst the other empires of the galaxy.
  • Hybrid - Step into the role of the leader of your favorite empire in the year 2165, with all of the territory, colonies and struggles that are to be expected from running an advanced empire.


Containing all of the empires you'd expect from the Mass Effect series, as well as a few of our own creation to help flesh out and balance the map. Each empire comes with unique traits, civics, origins, modifiers, and AI personalities.

  • Aralakh Kahmat (Tuchanka)
  • Asari Republics (Thessia)
  • Batarian Hegemony (Khar'Shan)
  • Cerberus (Cronos Station)
  • The Collectors (The Collector Base)
  • Courts of Dekuuna (Dekuuna)
  • The Followers of Nazara (Heretic Station)
  • Geth Consensus (Rannoch)
  • Gothones Remnant (Vindicta)*
  • Illium Corporate Interests (Illium)
  • Illuminated Primacy (Kahje)
  • Lystheni Order (Sepkai)*
  • The Migrant Fleet (Migrant Fleet)
  • Omega (Omega)
  • Parnack Regime (Parnack)
  • Rachni Swarm (Suen)
  • Raloi Republic (Azedes)
  • Remnants of Rakhana (Rakhana)
  • Salarian Union (Sur'Kesh)
  • Sed'riicae Collective (Sed'riicae)*
  • Systems Alliance (Earth)
  • Turian Hierarchy (Palaven)
  • Vol Protectorate (Irune)
  • Vorcha Clandom (Heshtok)

  • Galaxy Map Expansion - Currently having only 400 systems, we are expanding the map to have multiple system counts, with an expanded number of clusters, systems outside of star clusters traversable by hyperlanes (albeit substantially slower!) and an updated and even more lore accurate Relay Network, representing not just Primary, but Secondary Relays as well.
  • Economic Overhaul - bringing every building, tech, and district in line with Mass Effect lore
  • Further development of the empires - Ascension Perks, Traditions, and unique mechanics
  • Independent Colonies / MegaCorps
  • New Shipsets
  • Rebalanced Warfare
  • Multiple Crises, including the Geth Incursion, Collector Threat, the Reapers and other potential threats.

@Germanarmy @Tex doesn't even have to be that much. All you need is the 5 dlc listed on the mod page + Aquatics for the Hanar according to the discord. You can get all those for under $30 USD on WinGamesStore [] right now.

Might be able to get them for even less if you check and are willing to buy from multiple retailers.

I saved a ton this way, and these are legit keysellers, not those sketchy grey market sites so nothing to worry about there.

@Germanarmy $148 isn't that much in the grand scheme of things. It will be more expensive after Jan 5th when sale ends. Act now or miss out.

It's ironic that what I want the most this Christmas is only this mod xD
Thank you for the enormous work you are doing and even more thanks for the pets and families that give you even more energy to continue.
I really want one of the voices to be Jennifer Hale :fingers_crossing: :fingers_crossing::fingers_crossing:

@Demiurge Yes your take is totally right! :cozybethesda:
Demiurge Dec 28, 2022 @ 2:34pm 
@zev, looking forward to 1.0! Although I am a bit dissapointed the migrant fleet, the collectors, and especially the reapers won't be in it.
Demiurge Dec 28, 2022 @ 1:59pm 
@Germanarmy, I'm assuming because there are certain mechanics that the mod uses that require the dlcs in order to work. That's my take on it, but I could be wrong
Germanarmy Dec 28, 2022 @ 7:21am 
this is so fucking stupid why do we need all the dlcs so we can play this mod?? i dont have the money for all this shit..
