Get the mod here! And if you want more Half-Rats, check out:

Parasomnia Source Code available here:

July, 1883. Half-Rats is, as he usually seems to be; down on his luck and fretting for the future. One fateful night, he carelessly decides to drown his sorrows with strong libations - and he runs up a tab at a pub he knows he can't pay...Remarkably; Instead of a reproachful speech and coarse removal, he is instead told a tale he can hardly believe. A tale involving great riches, but even greater peril. If he was not so desperate, he wouldn't conceive of embarking on what could be a wild goose chase to locate a forgotten and virtually unknown town. Half-Rats' doubts were abated somewhat when the publican shews his utmost sincerity - albeit in a strange and effusive manner - and draws him a rude map.

"Thank the lord, for he smote that place from the Earth in '81. We lived, but most met their destruction the night that liberating conflagration visited freedom upon us. We're the last of 'em...There was a vault in the bank, large sums of money would have been stole away there, safe. We vowed never to go back, to keep that place a dread secret until tonight."

The seemingly mythical town in question is referred to as "Eminence". With no other hope to speak of, and fearing that this may be treachery after all; Half-Rats is still compelled to begin this peregrination to his "El Dorado" with weapons at the ready. But he'll find much more than gold and banknotes before his journey is through. All is not what it seems, and he'll find a living, livid hell to contend with...And the close of a dilemma he'd all but forgotten.

Character Background:

Half-Rats – A somewhat educated gentleman who fell from grace long ago, but still retains a singular social fluidity and still holds fast to the moral compass of his upbringing, and has been known to rub shoulders with bad company, while also fraternizing with the upper class when he can – where some regard his kinship as a novelty at times. Likes his whiskey. He has a certain amount of mettle, and tends to show levity as a means of dealing with dire situations. He had heard the rumors of Eminence back in Detroit, and decided to embark on an adventure!

Half-Rats just wants to relax...who could blame him? He's been through some serious things after all. It's time for his favorite holiday, and he and Barnaby take off; heading up north to Half-Rats' cabin retreat...long thought to be a sanctuary from demons and noisome landlords. Their ultimate plan is to stay up late, watch Netflix, and catch Santa once and for all! They don their festive attire...


Grab some Wendy's...

The booze was flowing, and anticipation grew more, as an argument over which anime to watch played out ever more...

When out on the lawn arose such a clatter - Half-Rats drew his Colt and said...

"Damn it! What's the matter?

When, what to his bloodshot eyes should appear...Jolly Clown Demons to ruin their year!


Get ready for December 24th! You could sit there, hang mistletoe over your bathroom mirror and make out with yourself like the freak you are...or, you could play this and celebrate Crassmass with Half-Rats! No one will think you're weird or stupid if you choose the latter...If people don't normally celebrate Crassmass in your country, you can still celebrate it privately with Heath Games!

Also, be aware that great fun awaits you if you join the Heath Games Community Discord server. I don't care if you don't like Discord, just do it, okay? Here's the link!

I hope to see you there!

It's a tough one. Not sure if we'll ever get around to that.

Haha! I had played Fever Dream a while back to my enjoyment and then immediately tried this Parasomnia and got stuck on the tutorial. Much more freaky than the first title. ^_^! Plus I was having problems understanding a few things...

Does the cat work as expected? I point all the way across the map and press the corresponding button ("Z" I believe) to send the kitty there, but the fish only "drops" in front of me a few feet. I had assumed it was suppose to travel a bit further... Also what is the point of the cat as it does not go through fences, even with big spaces in them? And my game froze with the cat after I had dropped the fish it was not moving towards it, but instead still following me so I tried to the USE key on the cat and the game shut down.

The sword I would of assumed would block when the button is held down or only for a moment and then goes back at the ready. Instead it stays blocking for as long as needed. Also the kick itself would of been nice to have with all weapons, not just the sword, although obviously it would of needed to be mapped to a button all it's own. And the ability to kick even while blocking would of been nice, but due to the block is auto, I guess that would of made it over powered or cheap.

Lastly is it really suppose to be that dark? I had to turn everything up for both brightness and gamma and the game still feels too dark. I think that is what made the tutorial so scary and I agree it is a good mechanic, but even with candles lit the place is just dark, almost annoyingly dark, opposed to just scary dark. I there something wrong on my end or that the atmosphere you wanted to create? Perhaps these parts are far and few between in the actual game perhaps?

And the shopkeeper and the vending machines, shouldn't one have something the other doesn't? Like if it was too far to travel or too dangerous for the shopkeeper, shouldn't the vending machine lack something or have something that the shopkeeper does not have? So when you see one you wish the other was there or be thankful when you actually came across it?

Also again the voice acting is top notch in the tutorial! Great job.

Go to files or download it directly through Steam.

Half-Rats I need your help. I'm mapping for a while now and I want to know how the hell are you making those subtitles. Do you use game_text or do you use something else and how do you trigger them. Can you explain to me it would be sooo helpful. And by the way you're a heck of a modder,keep up the good work :D

Reply Good karma Bad karma+3 votes

It's the same subtitles system as PARANOIA if you are familiar with it where "scripted_sentence" does the job automatically. All you have to do is to add an entry in "titles.txt" with the same sentence code (the "!AA_BBBB" thing) and trigger that "scripted_sentence".

Basically, you can just look in our titles.txt file to see how they were implemented.

Titles! They are triggered by the firing of multi_manager threads, and they are timed to the length of the wav file. Ummm, it's been a while, so I don't know if anything special had to be done code-wise. That's a question I could ask Shepard. Hang tight.

I figured it out, don't worry about it Half-Rats.Thanks for the help though! Stay awesome!!

Awesome mod, quite a few improvements and additions over the previous 'Half-Rats: A Fever Dream' The story is pretty interesting and the maps feel a lot less linear compared to the last mod. It even has a cool little tutorial which is pretty helpful and not many mods do that. It really is one of a kind and the most work I've seen put into a Half-Life mod in the past couple years. The enemies were pretty well designed and were indeed very difficult especially if you're standing still. It was quite…
