Where's the Behind the Scenes DLC?
Some of you might remember that I promised a free behind the scenes DLC to accompany the release of the Iron Lung Movie. And now the movie's been released for awhile, and there's still no behind the scenes DLC. So... I wanted to fill you in on why that is. Is the DLC still happen

'What the f**k': Iron Lung creator puzzled as Markiplier's film adaptation quadruples its budget in one day, beating out Melania and Send Help at the box office
If you're a fan of Iron Lung, the indie horror game from Dusk creator David Szymanski, you may want to get used to hearing the following five words: "You mean the Markiplier movie?" YouTube phenom Mark "Markiplier" Fischbach's long-awaited film adaptation of the 2022 sub sim has

Use magic spells and military surplus explosives to topple an evil crime syndicate hidden beneath a prestigious wizarding school. Learn spells, engage in espionage, and spread lore-unfriendly chaos.
Secret Agent Wizard Boy and the International Crime Syndicate is a comedic sandbox with a complete lack of safety nets or boundaries. Players are free to indulge in the full abject chaos of untethered physics simulations and uncontainable emergent gameplay, using a toolkit of magical spells and items to solve problems in ways we cannot hope to balance against.
Wizard Boy can also team up with other Wizard Boys in cooperative(?) multiplayer to explore (blow up) the castle together and thwart the evil International crime syndicate S.P.I.D.E.R once and for all!
FEATURES

A multitude of spells to learn and inflict on others
Chaotic, barely contained physics-based mayhem
Open-ended goals to accomplish (or ignore) however you see fit
Online co-op, although actual cooperation is unlikely
Retro-themed third person action, straight from the days of Unreal Engine 1
Landmines and other non-magical ordnance

Butcher's Creek is out now!
A troubled loner with a hunger for cinematic gore finds himself on the other side of the camera when rumors of authentic snuff videotapes lead him to an abandoned cabin near Butcher's Creek, Pennsylvania. What starts as illicit urban exploration becomes a fight for survival when
A troubled loner with a hunger for cinematic gore finds himself on the other side of the camera when rumors of authentic snuff videotapes lead him to an abandoned cabin near Butcher's Creek, Pennsylvania. What starts as illicit urban exploration becomes a fight for survival when he's captured by a gang of sadistic killers. Now his only option is to pick up a box cutter, a hammer, a pickaxe, or whatever else is at hand, and unleash a little video violence of his own.
FEATURES

Use hammers, axes, pipes, 2x4s, box cutters, and more to brutalize anything that stands between you and freedom
When all else fails, the level itself can be a weapon. Kick props into enemies, or enemies into environment hazards.
Photograph gruesome murder scenes to fulfill your dark desires and regain lost health
Explore decaying farmhouses, collapsing factories, and seedy strip clubs in a forgotten corner of the Appalachian Forest
Experience a unique aesthetic combining the gritty shot-on-video look of found footage with the photosourced visual style of Source Engine games

Secret Agent Wizard Boy was a normal Wizard Boy on his way to his first year at Wizard School until he received a message from MI6.

And so Wizard Boy started his first year at Wizard School, trying to uncover the mysteries that lay before him.

Winston arrived at a solution to the moral decay of his town.
He called out to hell, and hell answered. The human body could, hell promised, be twisted and stretched into a kinder, more equine shape. Winston's town, now filled with ignorant hate-mongers, could instead be filled with magical ponies, if he could provide a factory in which to make them. Winston thought they would be beautiful, gentle, and good.
Hell had other plans...
The Pony Factory is a short action/horror game inspired by Doom 3, with a darkly comedic story, striking black and white visual style, and visceral FPS gameplay. This is an updated standalone release of the original game, which was created in 7 days as part of the Dread X Collection 1.
FEATURES

Meaty FPS combat against highly agile foes who will attempt to evade and flank you.
Darkness is your enemy! Use muzzle flashes, sparks, sound, and other clues to track foes during combat.
High contrast black and white aesthetic inspired by early 1950's science fiction films.
A short minimalist campaign that can be completed in about 30 minutes.
Numerous improvements from the original release, including many new quality of life features, balance and game feel improvements, new story and gameplay content, full gamepad support, and of course bugfixes!
My brother John Szymanski (director of My Friendly Neighborhood) assisted with this version and will be receiving half of the royalties in an effort to provide him with enough income to continue game development until he begins receiving money from MFN.
John also released his own game today: a tense puzzle/horror game called Exiled:

Iron Lung dev responds to accusations that he's only doing this for the money after a $2 price hike: 'Yes ... I make games for a living'
Iron Lung, an indie horror game so popular it's getting a movie adaptation starring Markiplier , has raised its pricing on Steam to $8 (£6.70), a price hike of two whole dollars. For some reason, this has upset people to the point where the game's developer David Szymanski felt t

Cheats Update!
As of today, Iron Lung now has a few fun cheats for you to try! To activate a cheat, type the appropriate command into the computer terminal at the back of the sub. Cheats can be stacked (if you dare). There are only a few at the moment but I hope to add some more later on.
Currently, you can use the following cheats (which are also listed in cheats.txt in the game's install folder):

chclear - clears all cheats
chnoir - activates black and white visual mode
chview - allows you to see out the front porthole
chrave - makes the lighting more colorful
chava - adds a speaker to the Iron Lung
chvest - gives you a light
chmark - activates 'Markiplier Mode'
Halloween Sale
Iron Lung is going to be 20% off as part of Steam's Halloween sale, which starts on October 26th and ends on Novermber 2nd. This is a great time to tell your friends to pick it up because...
Price Change
...after the end of the Halloween sale on Nov. 2, Iron Lung's price will be changing from $6 to $8, and I want to make sure everyone has ample warning and time to buy it at the current price.
This is the only price increase I plan on doing for Iron Lung (I believe any more than $8 would be unfair), and as before all subsequent updates and DLC will be free. That includes a large collection of behind the scenes photos I plan on releasing as DLC once the movie is out.
When I first released Iron Lung I wasn't confident that people would resonate with the odd concept, and I expected to simply release it and move on. Now that the game has seen (and will probably continue to see) updates in content, features, and usability, I believe $8 is a fairer price, more in line with what similar horror games ask, and more sustainable for me over the long run.
Since my intent here is not to gouge people for money, but rather to make sure Iron Lung is priced competitively for the long haul, I again want to emphasize that if you know anyone who might want Iron Lung in the near future, make sure they know to grab it during the Halloween sale from Oct. 26th to Nov. 2nd.
