Welcome to the community! First, I just wanna point out that it’s important to read the rules! If you click more, then FAQ, you can read the rules to get the gist here!
Now for the actual help! You can use a life cycle or knockout manager, but I personally like the life cycle better. If your using the life cycle, make it so when a player is knocked out, make sure not knocks out, it can send a channel to reactivate all the sentries again!
If your using a knockout manager, it’s pretty similar! Make it listen to player, then make it send a channel to reactivate all the sentries again!
Hopefully this helps, and if you need any more help or have any questions, feel free to ask me! Once again, welcome to the community!
