Developer Notes

 

Hello guys! I did find some free time to investigate some bugs with X_17 spawn behaviors that actually needed some small but important changes and also to improve (once again) the X_18 current AI system, now it's assured that most of his behaviors will be correct and there's still some work to be done... X_18 is really unique and complex, there's some things planned as I said, but can't tell much for now, still need to investigate, check some API stuff and try to discover what can be possible.

 

Note: this mod is still WIP, and much content and changes will be done with feedback and my vision of this project. Please be free to give any suggestion or comment about anything you may wish. Thanks!
