Alpha 15 Released

Hello everyone, it is now time for the Dangerous Rays Alpha 15 update release !

August has been a quite busy month for us with the launch and the success of our Steam Greenlight campaign and the fact that i took one week of holidays. That’s why this Alpha 15 update is not as big as expected and why we delayed some features. Anyway there still some interesting things to see.

First i have made a completely new sound engine, based on FMOD technology this new sound engine brings some very cool features like a proper support of 5.1 and 7.1 speaker systems, improved hardware compatibility, faster processing time and a lot of other various improvements. This should improve the game experience a lot in the future when more sound will be added in the game.
A new AI navigation system have been added, this system is faster and support “crowds” so NPC are able to stay in groups and avoid each other. We are planning to increase the zombies density as soon as the navigation will be cleaned up. Be aware that the system is in prototype state at the moment and you can expect some navigation bugs from time to time, especially if you are loading a saved zone. I am working on those remaining issues. Once this navigation system will be clean enough it will be used to add the first animals in the game and then some new monsters / mutants.

3 new guns have been added by Mxthe and he also changed most of gun fire and reloading sounds. Don’t forget that you can use “actor_spawn” console command if you want to test guns and other items quickly. 2K9CON have made a nice list of spawnable objects and a quick tutorial to show you how to spawn objects at
Other than that you may find some various small improvements in different areas of the game and a nice batch of bug fixes.

At least two updates should be released in September because we can get back to work properly now after this crazy month. We will update our Roadmap very soon.

You should receive this update very soon in your mailbox. Have fun and thank you for your support. :)
