    Complete Project
    This product contains a full Unreal Engine project folder, complete with Config files, Content files and .uproject file, which can be used as a template to create a new project.

If you are working on a single player open world game I suggest you get the single player pack instead.

The Open World AI Spawn system re-designed for multiplayer experiences!

All the spawn and de-spawn logic is taken care off server side so there's no extra work for the clients.

This package contains a very accessible spawn system that you can easily combine with your own AI.

The spawn system makes sure that when there are no players around, there's no AI around.

It also allows you to spawn different groups of AI and add randomization. It's been made 100% in Blueprints and it's easy to read/expand upon.

If you are working on an open world game, or a game with bigger levels this system will probably help a lot in performance. It will also help you save time by quickly setting up spawn points.

This package contains some basic AI in there mostly done for demonstration purposes. (Done in Blueprint)

AI included in this package:

  • Roaming AI (Walk around to random locations within a set area)
  • Stationary AI (example: vendors)
  • Path AI + Path system (An easy to use path system so you can set-up AI paths in a matter of seconds)
  • All AI can be friendly or Zombie.
