PLAYTEST #7

Since last year, Antimatter has gone through six public playtesting sessions labelled as “demos.” They often lasted for a weekend and were intended to collect bug reports and feedback.

While they provided invaluable feedback, they were too accessible to players expecting a complete game, despite the in-game warnings and forms.

Using the tools provided by Steam, it is now possible to offer a more robust playtesting solution while keeping it free and open to anyone willing to participate.

What is a playtest ?

  • A playtest is a temporary testing session conducted on an unfinished version of the game (alpha).

  • Its purpose is to identify bugs, gather feedback, and test features with a wide variety of players. You should expect technical issues, incomplete content, poor balancing, and other rough edges.

  • A playtest is not a demo and is not intended to represent the quality or content of the final game.

When is the next playtest ?

  • Before the 1st of october 2026.

How do I join ?

  • You have to join the official Discord server, and look for the forum topic and post here Playtest wait list

  • Seats will be limited at first but gradually increased in number.

  • You will be warned before the playtest starts.

How to suffer play ?

  • While a playtest is active, it can be downloaded directly through Steam. just like any game in your library.

Are there any requirements ?

  • Only some availability, but no pressure! Please join only if you are willing to invest some time in helping improve the game.

    You do not need any previous experience, special skills, or a powerful computer. The goal is to include a wide variety of player profiles. (Noobs are welcome)

  • The playtest is free.

Non-Disclosure Agreement

  • As a playtester, you must not share footage, screenshots, or information about the playtest on social media platforms such as Reddit or Facebook, or on video platforms such as YouTube, Bilibili, or Dailymotion.

  • You may discuss the playtest and share materials only on the official Steam forum and the official Discord server and for the purpose of improving the game.

  • If you are a content creator or journalist and would like to cover the game, please contact me directly on Discord (Geo) to arrange a specific agreement allowing you to do so.

  • Breaching these rules will result in a permanent ban from all future playtests and may lead to action being taken to remove the leaked material.

Be advised:

  • Your playtest access may be revoked at any time, including to refresh the playtester cohort or remove inactive testers.

  • Playtest access does not constitute a purchase or a gift and does not include customer support
