The purpose of this mod is create an atmosphere of tension befitting of an HP Lovecraft story. Shadows play a huge role and light even effects certain monsters. There are advanced and difficult puzzles mixed with some tense combat. Ammo will be scarce, so the few guns that are found will be quite precious.

The setting takes place on an island, mostly within a cave. The player will encounter awesome sights such as subterranean rivers flowing with deadly liquids, an underground pyramid of the Aztecs, and much more!

Special Features Making This Mod Different:

The mod is EXTREMELY long. Over the course of three years it grew so much that we estimate it to be somewhere in the area of 10+ hours of play. This puts it's length as longer than most commercial titles.

One of the reasons why the game is taking so long has been the AI. To anyone who hasn't dealt with it, it is a nightmare. There is a reason why many commercial games have broken AI and tons of bugs. Still, I digress, let me tell you about our own AI.

When I first started working on the project AI was a problem that was very significant. Thankfully over the last few months I have hammered out all the problems allowing the AI Navigation to be calculated without errors. This has been an eternal blessing as it removed most of the problems we had been having.

In the screen below you can see how the AI points have to be individually placed because of the complicated and narrow interior which the AI has to interact with.

The player is going to have to run as there are far too many attackers to engage. This meant that I had to make the AI very smart and not predictable. This was accomplished by a large amount of code and the layout you see above. The AI has the capability to leap gaps, hurdle walls and get around other objects in order to hunt the player.

This first chapter will hopefully remain the most challenging area to develop as the other zones have limited amount of AI to worry about. I am expecting the development of the areas to go much faster than chapter one.

I hope you enjoyed this look into the AI of the Island of Cthulhu and keep a look out for the video that is coming soon that will demonstrate their advanced smart capabilities.

Nice to see another person also making a horror themed map/mod for Crysis. Keep up the good work, those brain spiders look great.

This is looking really good so far! I don't like the idea of the shredded nanosuit (i think you should just get rid of it), but other than that, it's great!

Just curious, is this going to work with Warhead? Or am I going to need to pick up basic Crysis?

We are looking into that. We might be able to release a version that works on Warhead, but as of now it is only working on Crysis. Warhead wasn't out at the time we started. The engine is Warhead is essentially the same, the problem would be if it's possible to pack up the assets from Crysis that are needed for the mod to work right.

We have actually extracted some of our assets out of Warhead so in a way it could be possible.
