Hypersomnia Patch Notes & News

Illuminated muzzle flashes, simplified recoil - now easy to learn!

Pythagoras of Samossteam_community_announcements

282d ago

\ - 2025-10-26

Every gunshot will spawn a legitimate light source for a split-second that casts shadows - this completely changes the feeling of every shot. If you dislike this, you can configure it from Settings -> Graphics -> Muzzle flash intensity.

Recoil is now predictable and only goes up instead of sometimes down and up - so you can now easily learn it!

Minor fixes:

Bots won't buy Amplifier arm or Blunaz, to be less annoying.

Overhauled the main menu for better presentation.

New background, sorted out the ugly-ass buttons for socials. Also changed the font from Liberation-Sans to Ubuntu-Regular. Linux players will feel at home!

New weapon - Bilmik. It's Bilmer 2000 but without the suppressor.

Pythagoras of Samossteam_community_announcementspatchnotes

360d ago

An economy rifle for Metropolis ($2800). Has a slightly higher recoil than Bilmer 2000, is loud, but is also a bit lighter and cheaper. And more maneuverable since it's shorter.

Enemies drop coins now! New gun: Vindicator (reboot from 2018).

Pythagoras of Samossteam_community_announcements

363d ago

\ - 2025-08-08

Added

- Enemies now drop coins from exploded corpses! You have to physically touch them to collect your reward. Watch out though - you will drop the coins you collected if you die before the end of the round!

- Resurrected unused gun: Vindicator. An economy rifle ($2500) specific to Resistance. Has 35 bullets, so more than Galilea, but less damage than Baka47 (32 vs 40) and is as slow firing as Baka47. It is however way lighter and has almost non-existent recoil.

Changed

- Balance: to account for the fact that you now have to walk to get the kill awards, all awards are now multiplied by 1.5, as well as dropping an additional $500 for a headshot.

- Balance: SMGs are more affordable now.

- Balance: Galilea: 34 -> 24 bullets, price: $2100 -> $2200

Fixed ranked servers not connecting

Pythagoras of Samossteam_community_announcementspatchnotes

375d ago

\ - 2025-07-25

Fixed

- Fix broken ranked servers not letting in any clients.

Changed

- Balance: buff `pro90` headshot radius multiplier from `0.6` to `0.85`.

Tech details

That was another bug that was only made apparent thanks to introducing bots.

- Indirect cause: bots were just playing warmup in perpetuity, causing world state to bloat.

- This is because when bots play, `is_idle()` is mistakenly reported `false`.

- This caused the maps (and thus the current round) to never change once `when_idle_change_maps_once_every_mins`.

- Maps now correctly cycle once every 15 minutes on ranked servers so this will never have a chance to happen again.

- Direct cause: the world and game mode round state growing in perpetuity as bots continue to play the same "warmup" round indefinitely.

- `cosmic::set_specific_name` wasn't cleared when a bot entity was deleted.

- `knockouts` history (the list of kills) was growing indefinitely as it is only cleared on round restart.

- `awards` history as well.

- All of these are transmitted through the network on new connections - but the limit is only `2 MB`.

Fixed deep netcode bug

Pythagoras of Samossteam_community_announcementspatchnotes

380d ago

Player was sometimes teleported, or getting randomly killed by bots even though it still walked on the screen. The footstep smokes were there but no bot was visible. Technical: - This was because of the decorative organisms (e.g. fish on `de_cyberaqua`) mistakenly using the same RNG as the simulation logic. - Normally when state desyncs, it is detected by the client - a state hash that differs from the server's is seen and a resync from the server is requested. - Not this time - this bug was apparent on the predicted game world which only exists on the client. - When the client is alone on the server, their predicted game world is usually spot on and might never get corrected for a long time until a random spike in lag (latency affects which simulation step your inputs might get applied to, so the **more stable your connection was, the more often this happened** as the predicted world was corrected more rarely). - However if that predicted game world has a different advance logic, the predicted and the referential server world might start diverging exponentially. - This is what happened here - within the predicted world, I purposely disable simulating fish to save processing time, assuming that will not break determinism of the rest of the simulation, but I haven't realized the fish are using the same RNG as the logic. Fish requesting next random values from the RNG causes the next requests to be different for the other simulation logic later down the road.

Fix frozen crosshair when holding a mouse button. CTs see planted bomb location.

Pythagoras of Samossteam_community_announcementspatchnotes

411d ago

- There was a super annoying glitch on Linux distros with X11 window systems - when switching between windows and back to Hypersomnia, the crosshair stops moving whenever you hold a mouse button, making shooting very uncomfortable. - Metropolis players can now see a bomb indicator once the bomb is planted. This is to make the game easier on newbies because some maps have several bombsites.

Fixed Linux version not launching

Pythagoras of Samossteam_community_announcementspatchnotes

422d ago

Steam has some serious problems launching AppImages recently, so I just added --appimage-extract-and-run to default launch arguments to not have to worry about this forever.

Perhaps on Steam, I'll ship this as an unpacked folder in the future instead of an AppImage.

Added bullet shadows.

Pythagoras of Samossteam_community_announcementspatchnotes

425d ago

Can turn them off in Settings -> Graphics -> Draw bullet shadows. Other changes: - Implement nickname-based authentication for LAN parties so local ranked matches between friends can be played without Steam - this means the match will be properly frozen in case somebody's client crashes and they'll be able to reconnect to continue. - Disable packet reliability for Web builds - it was mistakenly enabled. This will improve Web based experience. - Upgrade freetype2 to fix a security vulnerability.

HYPERSOMNIA IS NOW ON CRAZYGAMES.COM!

Pythagoras of Samossteam_community_announcements

727d ago

🎉🎉🥳🥳🥳 WE HAVE RELEASED ON CRAZYGAMES.COM!!!!!!!!!!!! 🥳🥳🥳🎉🎉 https://www.crazygames.com/game/hypersomnia You can sign in with Google or Facebook to play ranked matches with your CrazyGames account! CrazyGames is a web game portal with 30 MILLION UNIQUE USERS monthly, and Hypersomnia is finally tapping into this market - we're on the front page!!! PREPARE FOR A WAVE OF NEW WEB PLAYERS! It was hell of a grind to get to this point... half a year of porting to the Web, and additional two months of integrating with crazygames (porting the game to a single thread, adding sdk, 4 rounds of feedback etc.) - this is, indeed, a crazy milestone for the project! The game is now fit to be added to many many other portals offering free browser games - in fact, crazygames itself will distribute it to other sites!

If you had broken faction colors - see steps to fix!

Pythagoras of Samossteam_community_announcementspatchnotes

735d ago

There was a bug in the config saving routine that is now fixed, but some of your configs might already have saved broken faction colors - e.g. blue for resistance, gray for metropolis. If you experience this, you can simply go to Settings -> Open user folder in explorer. Then edit the config.json file (it will be highlighted) and remove the entire "faction_view" section. Alternatively for a quick solution just press Settings -> Reset all settings to factory defaults and configure your game again from scratch. Sorry for the inconvenience!

Netcode fixes. Use JSON for configs now. Manage multiple server instances.

Pythagoras of Samossteam_community_announcementspatchnotes

771d ago

Game settings have been reset. Your old settings can still be found in user/config.lua for reference (Settings -> Open user folder in explorer), but you need to set them again manually. Forgive the inconvenience! All other user data (maps etc.) remains 100% intact. We have migrated from LUA to JSON for improved security, efficiency and Hypersomnia codebase simplicity - removed two major dependencies! On a positive note, you now don't have to worry about copy-pasting someone else's config which could previously potentially execute malicious lua code! I would have to do this at some point on the way to scripting because the old Lua version has to be replaced with Roblox's Luau dialect. Great news community server admins! You can now manage MULTIPLE INSTANCES with a SINGLE SERVER PROCESS! No f*ing around with 10s of appdata folders! No 10s of configs flying around! Just pass this to one of your existing ranked server configs: "num_ranked_servers": 4, "num_casual_servers": 2 And a single AppImage process will automatically manage several ranked + casual server instances with incrementing port numbers and name suffixes! This was done to prepare for crazygames.com release so we can instantly scale in case of a sudden influx of players. Other fixes: - Netcode improvements: the game goes back on its feet faster after a lag spike. I upped the maximum number of messages per packet which was too low. - Fixed a nasty interpolation glitch on connect. - Auto-assign based on team score, THEN player count. - Marginal balance updates: Deagle muzzle vel: 5000 -> 5100 (+2%, so it's viable against the revolver), Szczur kill award: $600 -> $900

HYPERSOMNIA now in your BROWSER!

You can even play RANKED MATCHES - the web version lets you sign in with Discord! You can still play as guest on casual servers. Happy slacking off at school and at work! Let me know on our Discord if you experience any issues as it's still in development. This is a MASSIVE milestone for us - with the web port ready, we will soon be releasing on crazygames.com - this should bring a whole new wave of players!

Hypersomnia at PolyLAN 39 in Switzerland!

Pythagoras of Samossteam_community_announcements

816d ago

Although a little late - I'm extremely proud to announce Hypersomnia is played at this year's PolyLAN event between 10-12th of May! The first tournament was held with 12 TEAMS of 2 competing in Hypersomnia for the first time ever in real life! Incredibly grateful to all valiant contestants! {STEAM_CLAN_IMAGE}/44781208/b6b5254a047909d89475562de2eae28af7b4fbae.jpg The duo at the bottom right have been preparing for months, and, to nobody's surpise, they enjoyed a pretty much landslide victory, winning all 6 matches they partook in! I would like to thank Legrems, the core event organizer for choosing Hypersomnia to be on this event. See https://polylan.ch/ for more information.

Game didn't launch - Missing OpenSSL DLLs

Should now work fine.

Nerf Deagle, buff Cyberspray and Pro90.

Pythagoras of Samossteam_community_announcementspatchnotes

834d ago

Deagle: Price: 1200 -> 1600 Muzzle velocity: 5400 -> 5000 (Datum rifle is 5100 for reference) Award: 900 -> 400 (like ak) Weight: 6.95 -> 8.01 (example measured walking speed: 870 units -> 850 units) Pro90: Penetration: 20 -> 50 Muzzle velocity: 5050 units -> 5200 units Cyberspray: Muzzle velocity: 5700 units -> 5950 units

Low FPS (

Pythagoras of Samossteam_community_announcementspatchnotes

847d ago

It was related to client falling way behind the server and interpolation performing wrongly as a result. I also deployed a massive optimization (or rather a fix) to the netcode that should improve performance when the network conditions are good - there was a bug that caused the client to resimulate the world every frame even though it was not necessary whenever it predicted the world correctly.

Crashfix when alt-tabbing, HRTF fixes for some headphones, updated OpenAL-Soft.

Pythagoras of Samossteam_community_announcementspatchnotes

849d ago

The app would sometimes close on its own when alt-tabbing. HRTF would sometimes show as unsupported for headphones that report themselves as 7.1 (the ones using DTS 2.0, e.g. Logitech PRO X Wireless Gaming Headset). HRTF should now be enabled on all headphone models increasing gaming comfort.

Game now feels smoother with Linear interpolation. Can Toggle walk/sprint.

Pythagoras of Samossteam_community_announcementspatchnotes

859d ago

This patch implements Linear instead of Exponential interpolation which makes the game incredibly smoother in the 144-400 fps range. There are also separate keybindings to toggle walk and sprint if you prefer to press them once instead of holding the key.

Hypersomnia with native Wayland support on Linux!

Pythagoras of Samossteam_community_announcementspatchnotes

866d ago

This patch comes with a manually built GLFW library with both X11 and Wayland frameworks supported natively.

Rare crash fixed. Linux build uses GLFW now. Minor fixes.

Pythagoras of Samossteam_community_announcementspatchnotes

867d ago

This update fixes an extremely rare crash related to multithreading. The Linux build now uses GLFW which fixes some issues with French keyboard layout and possibly gives a better fullscreen behavior. Other minor fixes: - Prevent "AFK!" kick when match is suspended. - Prevent kicking AFK spectators during ranked.

Now using GLFW as the window framework.

Pythagoras of Samossteam_community_announcementspatchnotes

904d ago

This should fix a lot of window positioning/sizing issues as well as cursor clipping and even some startup bugs.

📢📢📢 FIXED STARTUP CRASH!

Pythagoras of Samossteam_community_announcementspatchnotes

The game should now launch fine regardless of current locale.

📢📢📢 FIXED STARTUP CRASH!

Pythagoras of Samossteam_community_announcementspatchnotes

928d ago

Made some important bugfixes during the game's launch process. It should resolve all errors related to "try_generate_sanitized_filename" at startup.

📢 Important balance updates! 📢

Pythagoras of Samossteam_community_announcementspatchnotes

948d ago

In short: this update nerfs SMGs, dual-wielding, and buffs sniper rifles and utility grenades so they are all a bit more reliable. Dual-wielding walking speed penalty: 15% -> 22% (Nerf) Pro90 weight: 3.98 kg -> 4.84 kg (Nerf) (affects movement speed) Cyberspray weight: 1.47 kg -> 1.96 kg (Nerf) (affects movement speed) Cyberspray price: $2100 -> $2600 (Nerf) Hunter muzzle velocity: 10000 px/s -> 14000 px/s (Buff) Awka muzzle velocity: 11000 px/s -> 18000 px/s (Buff) Flashbang radius: 1250 px -> 2100 px (Buff) PED radius: 700 px -> 1100 px (Buff) Others: You can now throw grenades further while running. Dashing makes them go even further. Interference grenades now ignore armor. This means they are now extremely reliable for deactivating people's stamina for good several seconds. PISTOL STANCE HITBOX HAS BEEN FIXED!!! Previously, it was EXTREMELY HARD to get a hit on the pistol/smg-wielding opponents. That's because the hitbox, while rotated 90 degrees, still didn't match the silhouette perfectly - e.g. on this screenshot, you could shoot through the opponent's arm like this without dealing damage at all. This has now been fixed.
