About House of Nightmares with 0 comments by HippoKittie on Apr 24th, 2015

Hon logo Now on steam

House of Nightmares has been approved on Steam under the name "House of Nightmares b-movie edition" in early access! We have for the last few months been working on concepts and models for additions to the game to make it not only a better game, but to have more re-playability!

We will be adding in a whole new single player story following a different character as well as stepping away from the b-movie influenced ascetics! Along with the new single player story we will be adding in the long overdue co-op mode!

skull guy!

The co-op mode will be adding yet another story shared amongst 2 people! With the co-op mode we hope to also add in the ability for players to put in their own maps and creatures!

The game will be through the early access period at a 30% discount from the final price! Please take a look and tell your friends! We will be listening to the feedback from the game, making regular updates accordingly and most of all, the community will help determine how the other 2 modes will pan out! It has been a long and hard journey getting to where we are today and only the fans are to thank! Thank you everyone for believing in us all this time!

Hey guys, been on the group for a while but I don't think I ever really introduced myself here. I'm Daniel (most people know me as Dan, TheWalshinator or Walsh) and I'm the project leader at Walshinator Productions, where me and my currently small team are working on a first-person psychological horror game series called ALWAYS HUNTING, a prototype for the first of which (Jacob's Story) is currently in development.
Help is always welcome and greatly appreciated, so if you are interested in helping out or just want to chat (which I'm totally fine with), feel free to send me a PM or hit me up on Skype (thewalshinator1). I'll say now that we do not currently have a budget, so paid work isn't an option right now but might become available in the future, because I plan to launch a fundraiser campaign after the prototype's three levels are completed.

I don't think it's really a problem since UDK is almost fine as it is. My only grip is that the C++ source code is locked and we are now stuck with Unreal Script forever...

How are you using Unreal Engine 4? I thought that wasn't available to the public yet? It looks great none the less.
