I need a script that will make zombies spawn at the start of 'rounds' so to speak, but without spending 2 years placing enough zombies. Seeing as it's just gonna be a 'survive as long as possible' thing, If I survived say 250,000 rounds, I don't want to make it so that I have to put zombies in enough for that!
I also want them to slowly get stronger and their loot to gradually become stronger and more useful, but there are no beds for the player to level up in, so I can't make leveled lists.
This is probably really confusing, but I need the help!
Thanks
