What the developers have to say:

Why Early Access?

“While massively fun, Hypersomnia lacks content to make people stay.
I wish it thrives as a community-run eSports hub. We still need more customization capabilities like scripting to keep the game alive for years to come. Before these are addressed, Hypersomnia cannot be considered complete.”

Approximately how long will this game be in Early Access?

“Up to a year, which means until the end of 2024.”

How is the full version planned to differ from the Early Access version?

“I hope to add the following:
  • More high-quality community maps.
  • Deep Discord integration. (e.g. assigning MM ranks as Discord roles on our server)
  • Server-side scripting.
  • Bots, if additional multiplayer features aren't more urgent.
  • Fallback to relay if NAT traversal is impossible - extremely rare routers could prevent people from hosting a match (works with most of them though).

What is the current state of the Early Access version?

“The game is already fully playable with your friends over the network.
You can:
  • Fight for your rank in the global leaderboards! We have a rating system in place.
  • Play the classic Bomb Defusal mode (even up to 6v6) or Free-For-All where every man is for himself.
  • Use the built-in Editor to create custom maps.
  • Host your own server on your PC immediately from the main menu - even behind a router. This way you can choose any map and mode to play with your friends.
  • Host your own servers running 24/7 on a dedicated machine (or a VPS) that cycle custom maps of your choice.

Will the game be priced differently during and after Early Access?

“No. It's permanently free and open-source. No hidden payments. There will never be a way to spend money in Hypersomnia.”

How are you planning on involving the Community in your development process?

“Continuously sharing insights, reporting bugs and creating content on our official Discord server at - the home of our community.
This is where we will:

  • Collaborate on more community maps. They'll be added to the official collection where everyone can download them from the main menu.
  • Organize tournaments together to awaken the eSports spirit.
  • Balance all weapons so that the mechanics always remain competitive.
  • Share feedback on server scripting/administration capabilities so that Hypersomnia becomes truly extensible without limit.
  • Write custom game modes (once scripting is implemented) perhaps even creating entire campaigns.

Metropolis. Atlantis. Resistance.
