The End of First Access! Next: Steam Launch!

First Access on itch was a great experience, but now we are turning our attention to the launch of the game on Steam, which means that it's time to officially end the First Access program!

The Steam launch is looking like mid-August now! We've had a few delays, but are committed to putting out the best possible product, not hitting a date.

We will continue selling First Access keys on itch.io (at https://hofstudios.itch.io/doe ) through the end of the month of June, at which time we will disable updates to the itch.io version of the game. In July, we will begin distributing Steam keys to First Access buyers and all updates will be done there.

Build 42: New Classes, Items, HUD Redesign and Rebalance

The HUD has been redesigned a few times already but we had some new ideas. This delayed Build 42 by a few days but I think the change was worth it as the presentation is much cleaner overall. This will still be a work in progress so love to hear feedback or criticism!

We're excited to introduce the latest classes in the turn-based tactical RPG Depth of Extinction: the Wrecker and the Warden. The Wrecker wreaks havoc with his AOE minigun while the Warden is a defensive focused character who lays down covering fire to any enemy who fires on an ally.

We also introduced many new items and did a complete rebalance.
