Mavs Hard Mode is a add-on mod for SOMA that seeks to increase the difficulty of the main game by overhauling enemy behaviours and encounters.
Summary of Changes:

  • Death is instant. Tread carefully.
  • Enemies are faster and more aggressive with improved senses. If you can see them, they can probably see you.
  • New enemy encounters have been added, and slight changes to some level designs have been made to facilitate them. Forget what you knew.
  • Changes to enemy pathfinding. Assume nowhere is safe.

  • 'Knocked Unconscious' mechanic is removed and replaced with instant death. Note that some enemies will deal less damage when attacking from behind.
  • Footsteps produce more noise
  • Crosshair removed.
  • Flashlight strength is increased
  • Environmental hazards are more damaging and lethal. Includes things such as steam and electricity. Previously there were caps on how much damage they could deal preventing the players death. These have been removed.

  • Steam at the top of the stairs where the construct first spawns is now lethal and requires it to be turned off in order to progress.
  • The second construct encounter will occur regardless of what choice the player makes to divert power, albeit under slightly different circumstances.


  • More cluttering in the server area to make for trickier navigation.
  • Pathfinding and cluttering changes to the labs area for akers massive benefit. Do no assume you are safe anywhere.


  • Area outside Curie has been altered with slightly more cover and pathfinding changes.
  • The flesher in Lambda returns for real


  • Opened up the vents in the power room to provide a method of bypassing robotgirl if she is blocking the corridor.
  • Changes to many triggers related to the robotgirl encounter. Most noticeably she can now pursue the player outside of the power room.


  • Major changes to path nodes and patrol patterns for Jin Yoshida.
  • Minor changes to level design to facilitate new enemy encounter.

  • A new proxy now patrols the Theta Labs with Akers. Usually hangs around the security office.

Recent changes to my real life circumstances mean that going forward I will be likely quitting gaming all-together in order to focus on the more important things in life. Consequently this means I will no longer be updating or supporting my mods for SOMA and Amnesia Rebirth.

As of December 2021, all my mods should be working with the current versions of their respective games at the time. As we saw with the Chinese update it's not totally impossible that FG will release a micro-update that ruins everything and in the event of this happening it's likely that certain mods (Especially Mavs Hard Mode) will stop working.

As a result of this, all my mods are now completely open source. Modify them, re-upload them, continue working on them or even steal them and call it your own work. No need to ask permission or even credit me as I won't be monitoring the ModDB or workshop pages anyway.

The exception to this will be the later versions of Cutting Room Floor: Omicron that contain the restored patchwork man as this was done by another author, "Random Person" who you can contact on the Frictional Games Discord for permissions.

I have an error launching the mod with the "mod launcher" utility - as a base game addon; the errors I get, tell something of:

FATAL ERROR: could not load script for 'LuxInputHandler' 'base/InputHandler.hps' of class 'cScrInputHandler'

helper_game.hps ([values]) : ERR : No matching signatures to [category]
(...) Illegal operation on ''

Sorry for fragmentary report.

Hey mate apologies for the late reply.

I don't have any issues loading the mod myself. Additionally this mod makes no edits to the InputHandler.hps script so it is unlikely that this is actually an issue with the mod itself. Try verifying/re-installing the game. This mod was made on the steam version of the game but there shouldn't be any differences between legitimate providers.

I run it on 'Ubuntu', the game is a DRM-free version from the 'Humble Store'. Maybe this is some sort of "Linux" quirk, causing the issue; or the game adaptation to "Linux".

Is this recommended for someone whos never played SOMA? I've extensively played previous Frictional titles.

not on your first run in my opinion. You will be less likely to explore under the harsh conditions of hard mode, thus missing out on world building that is an integral part of SOMA. I'd recommend it after experiencing the base game.

Although to each their own, you might be able to tackle everything on your first go. It'll certainly be an intense experience playing it blind.

Is there a way to have the distortion effects back with other enemies? Only Fleshers seem to have it but not the rest. I tried to turn them off and back on in game and it doesn't make a difference.

The mod shouldn't disable distortion for any of the monsters (at least intentionally). I will look into it when I get the chance.

So I went past Akers and the Proxy at the Theta labs. The Proxy has no effect on my vision at all. Akers makes the camera shaky when looking at him but there's no distortion effects with the shakiness. But once I reach the proxy at the maintenance in Theta, the effects seem to work fine... Maybe they just don't work at the Theta labs. Maybe it's a glitch because the game is not designed to have two monsters at once?

THANK YOU for replying, not many modders do this, I appreciate it! :)

I just tested with the proxies in the Theta server room as well as the labs and both are causing the correct distortion effects for me.

Unfortunately I don't know what could be causing this on your end so I can't offer any advice beyond re-install the game etc.
