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!

If the video was too long to bear, to paraphrase - this is a reminder to check out the previous news articles I posted, as well as outlining some new developments that you weren't made aware of. Like skip-able dialogue, and the fact that Thanos has returned once more after taking a sabbatical, and is now Swiss - he's in a much better place in life and will soon be ready to dive back into Parasomnia 1.1. This time I've elected to use Version Control software so we don't run into the same horrible, evil situations we did before. AND, don't forget, all the problems you had with the weapons' speed, accuracy, rarity, secondary fire transition speeds? Gone now. And of course - everything's going to be more lit up.

Aside from all that, I professed my main goal in all of this - which is to establish a brick and mortar studio here in Michigan. There's a lot of talent coming out of our Universities and Community Colleges, and I'd love to keep it here in the mitten.

This is Shepard's skip-able dialogue. It's still WIP, but it'll give you a good idea of how this all works!

What else is up you ask? Heath Games Merch is in the works!


Yes, that's right! Stay tuned for Half-Rats Mugs, Shirts, Aprons, Phone Cases and...Love Pillows! Ever want to cuddle with Barnaby? Well, you'll soon be able to.

Well, that's all...FOR NOW! Good evening, Ratlings!

hey I got a problem with the steam version, I can't enter the sheriff constobulary map, the area where you first see the policemen and I don't what I'm doing wrong, I have the rifle and everyithing in the map should have been explored yet I can't gain access to the new area.

Reply Good karma Bad karma+1 vote

Since you have the rifle, I assume you have entered the police station grounds. In the area you first encounter the police officers, check for a door which is broken down. It will lead to you to an office, with a key on the wall. This will let you enter the police station ;) .

Did you run to the door you first entered? That door is going to remain OPEN, and close in the player's face when they are instructed to leave with the new objectives system to make that more obvious in 1.1. And by "Door" I mean Eminence's main entrance.

One question, why do the cops use the revolver animation when using henry?

Probably a glitch.

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…
