Download Half-Rats: Parasomnia - Mod DB

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!

First of all, here's this:

Once again, it's in PDF format, once again - it'll make great toilet reading on your phone or tablet. Hog up the public john like a poop-glutton as you read it, have a s**t on us! If you don't have Adobe Acrobat - it's 2017...just get it already, true fans won't want to miss what's in these pages. We've got a detailed history of Eminence, some juicy tidbits on your favorite characters, monsters and events - as well as a detailed timeline of events in the series. This thing really expands on the lore! Thanos did a great job on the graphics and making suggestions. His help really brought this thing to life, and you'll find it's a great improvement over the HRAFD bestiary. If you don't like it, you're not our friend, okay?

Now, on to 1.1 progress...

We thought hiding behind barrels and looking for muzzeflashes in the dark was pretty RAD, but a lot of people didn't, SO, we've been working on making outdoor areas with longer-range combat a little better lit!





Additionally - aside from our new hint icons, we have wonderful color-coded keys and locks, as shown here.





Then, there's the case of the missing Shotgun/Henry...I think we solved this one, wouldn't you agree?



Well ain't that a treat!?!

There will also be new audio snippets/clues that better explain things/gives clues to explorable areas. A lot of people missed all the goodies at the beginning of the game, and trust me, there were a LOT of them.

In other news - this went below the radar, but Ague's latest album "Dissolution" - is out, and the HRP OST is available on Steam for $1, or for free right here on Moddb. If you're interested in supporting Ague, feel free to visit the link below! <---Ague's latest album "Dissolution".


Thank you all for the support so far, Half-Ratters! You know who you are! If you're reading this, and have played HR:P and enjoyed it, I'd like to take the time to ask you to please cast a vote for us for MOTY, We also want to see some reviews! Either on steam, or right here on Moddb! We're counting on YOU and your continued support!

One of the reasons I like HL1 is because it doesn't require Steam and other interned-bound services (not a fan of such things). I have a legit WON copy and would be really gratefull if you ported your mod (the first part of which I've really enjoyed) to WON or Xash.

You can redeem your WON cd-key on Steam and Valve will give you the Steam version of Half-Life. You can install it, set Steam to "Offline mode" and install and play any Half-Life mod without the need to be connected via any online service to play them. I did not like Steam as well, but fact is that every Half-Life mod requires it now in order to play. You can wait for our Xash3D (and probably WON) ports, but that will take a while, since it's not our priority now.

I need this mod but I do not have steam because it damages my computer

Steam touched me in the bad place, but I had no choice but to go with it. I did it for you guys...The WON version's a long ways off at the moment. We're just trying to get the game polished with the 1.1 update at the moment. THEN we'll work on getting all the crazy extras out of the way.

I which way does Steam damage your computer? Either way, you need Half-Life on Steam to play Parasomnia.

From all of us here at Heath Games, thank you all for your MOTY 2017 votes, love and support :) . We did not make it this year into the Top 100, but that doesn't stop us from trying. Work is going strong on 1.1 and the update will come along with a lot of goodies. Until it launches, read the "Bestiary" to kill your time :) .

Thanks again for all your support!

damn! you didn't make it? you guys deserve a medal for the best HL1 technology since Cry of Fear and Mistake, having an almost perfect setting like Blood, great soundtrack (Auge rock on!), amazing storyline, awesome quality of graphics, and not letting it die. instead of leaving for months at a time and giving a screenshot or comment every so often, you kept us informed during development, and you programmed awesome AI for Half-Cat Cheroots, and all the while had perfect level design. I know its more of a review than a comment, sry. just wanted to say thank you for the awesome mod. also, the bestiary was written to perfection. again, good luck with 1.1. stay cool dudes, we're 14 days away from Christmas. also, when you move on to MOPAT, good luck.

Thanks, Krychur, I'm sure there's a few others who feel the same way. We got it last year, though.

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…
