COD Zombies slayer gamemode

[(minecraft)]

I would like a slayer mode where there are bot zombie spawners (like endless zombies) and the barricade brick (8x cube) after every wave in red text it will tell the wave the player is at
also if possible please make the purchasable weapon events :)

You can do this using the Endless Zombies game mode and some events.

last time the barricades crashed me is there a way to event the barricades, sure I can make the weapon shop but the barricades is the problem with me
