Epsylon - The Guardians Of Xendron


Epsylon is a game project based on the good old detective stories but taking it a step forward mixing it with an unconventional cast and a new game engine technology. Detective stories are in general static narratives with limited set of interaction and little replay value once the story is done. The player has next to no influence on the way the story unfolds. Here the Epsylon project hooks in and expands the game mechanics to allow the player to conduct investigation his own way. How the player conducts the investigation influences the world and people around him. An AI in the background reacts to the moves of the player potentially altering the course of actions. Besides the basic detective moves the player has access to some "characters" providing some special abilities that can be of help.

You are Georgo Valentino, a private eye. On your way looking to solve one of your longest standing unresolved cases you end up with a hunch leading to the parallel world Alpha-10. In this universe multiple worlds exist next to each other. Very little people know about this though. One of your friends, a scientist, does know. and he most certainly knows more than that. He has a special "friend" himself that he met while researching what is called the "Xendron", the multidimensional space. Arriving at Alpha-10 Georgo is quite surprised finding his "friend" having dropped off his little girl at his side as he has "own business" to take care off. You should learn soon that this little girl (Sean) has some special abilities that can be of help to you. And if that is not enough the organisation you end up with has two special "agents" (Odjin and Bahatos) at their disposal that have their own set of abilities to bring to the table. The interesting part? The little girl and these two special agents are dragons of different kinds. As it looks like they play an important role in the case to unfold.

Will you be able to solve the biggest case you ever had?


All your actions have large influence on the events in the world. It is better to conduct your investigation without force if possible. As you are a stranger in this world people tend to not tell you all they know so you have to find your own ways to gather the informations you need to crack the case. There are multiple ways to solve the case depending on how you approach the investigation and with whom. Be careful though with whome you talk and what you do. The underworld is watching you and will react to your snooping around. Counter measures can range from making "vanish" information you seek all the way to trying to silence you or people you got in contact with. Various features can help you on your way:

  • The Dynamic Investigation System allows the story to adapt to your investigation style. Information can be dynamically created and destroyed. If you are not careful certain information can become hard to find.
  • The extended conversation system prevents boring multi-line selection conversations. Furthermore topics can be talked about from the pool of information you know. Some people don't tell you all they know unless they trust you enough. Some don't tell you in fear of something in their past. Sean has unique abilities helping you to break through these mental chains. Or you can try to confront them with evidence or flaws to throw them off balance.
  • The past holds the clue to the current events. In certain situations Sean can use her abilities to catch a glimpse into the past. While this won't solve a case it could yield the puzzle piece you need to fit all together.
  • The interactive environment allows you to use objects in various ways including computers to snoop around emails and documents. Be careful though that the AI can notice changes in their surroundings.
  • The investigation system helps you solve your cases. Keep track of information about various entities in the world as well as the progress on your investigation. Most of the time you are not told where the information is you are looking for so use the entity informations as well as snooping around to find it. You have to find "a" way... "your" way... you don't follow a predefined way.

One of the key points is that the story is part of the game mechanics. It is not told to the player by hitting NPCs. The story is the main case in the investigation. So to learn the story solve the investigation. Depending on how you solve it you can learn more or less about the story. It is therefore useful to look sometimes deeper than requested. And who knows what influence your choices have on the outcome... or members in your team.

Demo Preview Reel


This year had been quite a ride in many ways as I'm certain many can agree with.

One of the major tasks had been to release the Drag[en]gine Game Engine to the public which hit version 1.4 recently. Once the most pressing bugs had been resolved the focus shifted back to the public demo.

For this the player feedbacks from the booth had been taken into account. Various parts of the game had been revised and improved. This required some extra work but it has been worth it. The playability improved a lot.

The main plan had been to get the public demo ready by the end of this year. This has been pushed back by a few weeks due to the above reasons. As a tooth sweeter in the mean time here a little pot-pourri from the public demo.

Don't forget to vote for Epsylon in the IOTY to show your support.

DragonLord - Do you need an Artist. I would be more than willing to help out where needs be. :)

P.S. - Where can I find the Binary version of the Dragon[En]gine? If there is one. I would like to mess around with the Physically based rendering pipeline.

Yeah I know it's not the fastest. But if you are forced to do all on your own things don't go fast. I'll though implement in the time to come some stuff which should help me to get things done faster. Not optimal but it should allow this project to get somewhere in a reasonable time.

I'm sure you know the 0 A.D. team a bit, that game's Alpha took 9 years I heard.
But yeah, we look forward to updates till then!

good job though, still on course. Respect!
