Originally released last year to great critical praise, the old-school-inspired Axiom Verge debuted on PS4 and PC but the promised PS Vita version of the game has still been in waiting with developer Thomas Happ providing an update on the portable version of the game.Happ provided a new blog post on the game's official website with an update regarding the PS Vita version of Axiom Verge, which was initially announced to be on the way but since then has gone quiet on updates, with no firm release date or window provided for its release.Happ explained that he "felt I owed the community a more detailed look at the issues we're struggling with, where we are in the process, and how much further we have to go," and went into more specific details in his post:

So here’s the good news: the game is ported. It runs and is playable! Anyone who has worked on a porting project can tell you that that represents the biggest hurdle. Going from ported game to polished and shippable ported game is much easier than going from non-ported game to ported game. In fact, one of the reasons I couldn’t give a status update on the port before was that there was nothing to show. It was all plumbing and wiring. It’s only when you get everything hooked up and hit the switch that it goes from 0-100 pretty much overnight.

So from here on out, our focus is on cleanup, polish, and bug fixing. Here is the current list of known issues with the game. Some of these sound like major issues, but in most cases, it’s just a question of going down the list and implementing each feature or isolating a few bugs. For the most part, this list is not necessarily in the order of which these issues will be tackled; rather, it’s primarily in the order of ease of understanding. Any feature listed as critical is something we feel we cannot ship without.

In the post, Happ provided a full breakdown of the major issues and fixes he is looking to make for the PS Vita version before it's released to the public, along with a short video of an alpha version of the port in action:

Happ concluded that while he doesn't want to share internal target windows for release just yet to avoid "[failing] to meet expectations and continue to disappoint those of you who have been so patient and supportive," he did say that the PS Vita version is "in the home stretch" and seems to be coming sooner, rather than later.

In addition to the explanation from Happ on the situation regarding the PS Vita version of Axiom Verge, he also mentioned through the game's Twitter account that Axiom Verge will support Cross-Buy with the PS4 version of the title, allowing those that purchase the PS4 version to get the Vita version for free. The game will also share its Trophies list with the PS4 version of the game, and Happ also implied the game will support PlayStation TV.

Axiom Verge is available now for PS4, PC, Mac, and Linux, with the PS Vita version currently in development.
