First of all, I'm new and I would just like to say hello.

Ok, so I have been playing this game for a little while and love it like everyone else. But, I had an idea that would make this game even more exciting.
Zombies.

You could add another server list for this game mode.

I was thinking about it and this sounds like a lot of fun. You could start out like you would on a regular server but after a few seconds, zombies would start attacking.

Of course, you could put up walls and but zombies could break blocks. You would need to build some sort of fort to take refuge in.

There wouldn't really need to be any new weapons (although that would be much more fun) but there would probably need to be an ammo refill every few waves.

That is all I have thought out so far, but it is your game so change it however you want. What do you guys/girls think?

Good or bad idea?
