Download SpaceAI Free Unity.
This asset can be a great solution to many game developers who want to build space sim games. It serves as a great platform for creating a variety of space shooter games and simulators. You can use it as an addition to your own space saga.
The asset includes an obstacle avoidance system, particles (explosions, guns), random and controlled gun switching, target search and identification. And also for now two 3D models, simple and intuitive system settings. Serialize classes into data, for more global solutions.
In next update (v2.0) will be added new 3d models of ships and turret system.
