Currently you can use a sentry for testing but sentries are limited as they don’t move nor engage. The spawners work for that but requires addental code and is missing events.
What I would like to request is that you can set the player spawner to spawn sentries “as” ai players and they are treated as players.
This means you don’t need to write additional code and you can better test the team dynamics with out having to get actual players in the session.
There are some game dynamics that are hard to test using the current way of doing it.
Friendly fire is a example of that
