Evaluation
Epsilon is no longer available for purchase on Steam — the game has been removed from the storefront. It remains in Early Access and was never completed or given a 1.0 release.
The developer, Christian Allen of Serellan LLC, posted a farewell message on February 11, 2017, explaining that years of effort — including Kickstarter campaigns, publisher deals, and personal loans — had not resulted in a sustainable business. He cited personal health issues and major financial losses, and stated he needed to move on. While he noted that Serellan LLC would remain a legal entity and expressed hope to update Epsilon again "as time allows," he was clear that it would no longer be a focus. No further developer communications have appeared since that February 2017 post.
The game's last substantive update was a feature patch in May 2016. The studio closure announcement followed in February 2017. The game was never brought out of Early Access, and development has effectively ceased.
Evidence
Developer Christian Allen posted a farewell message stating that none of his ventures to build a tactical shooter proved financially sustainable. He cited personal health issues and financial losses, and announced he was moving on. He noted Serellan LLC would continue as an entity and he hoped to update Epsilon occasionally, but it would no longer be a major focus. This is the last developer communication on record.
The game has no purchase options available — it has been removed from the Steam storefront and can no longer be bought.
