Objectives and Mission Scenario Changes Previewed

Some news:
  • DRM free platforms announced
  • We've hired a writer to help with story!
  • Updated release/beta schedule
Excerpt about Objectives:

Objectives all have different “final” missions that are more in line with the narrative and provide a more interesting payoff as a result. A few examples:
  • Hostage Situation - rescue a hostage from a locked room and escort them safely out of the facility
  • Terrorists Strike - disarm a bomb placed in a facility by raider
  • Rogue AI - hack terminal to weaken the AI so you can then disable their primary server. The AI won’t go down easily and will leverage facility defenses to repel you.
We’ve got a lot more scenarios that also will feature unique missions. Hopefully this will address the “more variety” feedback that I’ve seen from a few of you.

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 the free beta Steam keys to First Access buyers and all updates will be done there.
