Discover the zombie-apocalyptic nightmare in this mystery adventure game!

Biohazardous is a third person mystery adventure MOD - based on the Source Engine.
I'm not only trying to recreate the original atmosphere encountered in classical survival-horror games alá Resident Evil. What I also want is to give this genre a new charme along with some pretty newer gameplay ideas combined with a mysterious, puzzle-filled story line.

And yes, there are zombies out there!

Biohazardous will be an episodic adventure and starts off with the prologue. Within the prologue you'll learn the basic mechanics of Biohazardous along with the task to break out of the apartment where Catherine is trapped. But to escape you'll need to regain her memories on how she got there.

Along with a new genre on HL² mods, new features are needed to ship in.
The prologue will come up with:

  • Fully-fledged static camera angles
  • Tank-controls
  • Auto-aiming and optional, toggleable lasersight
  • Zombies!
  • Inventory and pickupable items
  • Item based puzzles as well as physics puzzles
  • However... Zombies!!
  • Overview map which can be called from the inventory; offers information about your position, locked doors and more
  • Many pages of notes and files to read
  • Ingame cutscenes as well as pre-rendered ones
  • Character state can be read by the characters model; if Catherine is injured, you will see that
  • Zombies! Again...

Q: Is this a Resident Evil remake?
No, it's just an individual game with own ideas and ways.

Q: Release date?
A: Nothing to say here, first I want the basic mechanics running as smooth as they should. Let's just say: I want the 'sub-engine' for this type of genre completed first!

Q: Do you need help?
A: Who doesn't? But at the current stage, there's no point in setting up a full team. So... No, not yet.

Hey folks!

Even if there is not really new to show you within pictures or videos, there are some words to say.
First off, Biohazardous is going to use the SourceSDK 2013. I've ported the mod to this newer branch which is necessary to ensure all mod tools are working as they should.
This DOESN'T mean Biohazardous will feature the VR-Mode. Including static camera angles, there's no avail with the Oculus Rift.

Second (and more interesting I think), the very 1st Alpha Version.
I have set myself an internal deadline and established a roadmap to improve the development of a first playable alpha build.

A few things which will be available at the first alpha:

  • Fully implemented tank controls & fixed camera angles
  • Some puzzles to solve
  • 'Points of Interests': Entities placed by leveldesigners. These are small areas where you can interact with the environment. For example, if you interact (use-/action-button) with a bookshelf, it will show up some text and even the characters voice telling you if there's something interesting. There are many possible applications for this entity like puzzles, items to pickup, details/background story, doors and much more!
  • 15-20 minutes short demo level featuring and demonstrating the stuff stated above

Features which WON'T be included in this alpha:

  • Inventory
  • Enemies, weapons and fighting
  • Story
  • Typewriters
  • anything else ;-)

Well, it's a lot of work to get the basic framework as smooth as it should be. That's the reason why most of the features won't be included in this very first alpha version. But it's fun as hell!

Oh yeah, almost forgot it.
YES, there will be a ruthless pharma organisation!

Already have to show something for you! Worked and tweaked on the thirdperson code and set up the fixed camera.

When's the next news post? Assuming the mod hasn't kicked the bucket, that is.

Zombies, zombies, zombies ok here's a question! Will your zombies be the slow, shambler kind or the fast,usain bolt kind? Also, will they eat brains?

What's wrong with zombies? (Everybody loves them! ;-) )
You'll find those slow, shambling types of infected in game, but who knows what else? I can't say much about that yet. I want to get done a playable build first.

I know, but shambling zombies will always be more atmospheric and creepier. AArgh I won't bother you no more, you do your thing, I'm sure it'll be great. God speed! :D

Also, I think fast ones can be very difficult to handle with static cam angles and all that stuff. It's just a slow-paced gameplay style.

But I haven't thought about enemies and their gameplay design yet.

And no, you don't bother me.
