I had an idea that You would be able to buy like fences, walls, and stuff that could block the robots path but it had HP so it can be destroyed and you have to buy it again. They could only be bought before the wave starts and likely making it more hard if it is placed in the wrong spot it could be useless. I was also thinking of having the tower defense plugin here but have each tower have hp and when it gets to zero it gets destroyed. Then you have to have to pick it back up.

I also just came up with 2 difficulties. Chill and Run. (I guess)
The "Chill" mode would allow for walls to stay until they are destroyed and maybe more money as well as picking up towers after they are destroyed. The "Run" mode would remove the walls at the end of the wave or you might not be able to buy them again and towers destroyed makes you have to buy them again and maybe less money with more robots as well as them being harder.

Thoughts?
I am not sure if this exists but I just kinda came up with it.
Sadly I don't have any useful knowledge in map design or plugin coding.
