Do you like minigames? Do you like choppers? Do you like ninja shenanigans? Do you like carnage and mayhem?
If not, you may wish to stop reading.
If that sounds good to you, continue to read as I explain my latest minigame.

The concept is simple:
Bad guys AKA "zombies" or "demolition workers", spawn in a box and are held there for twenty seconds.
(I don't know, maybe they're on their lunch break).
Once they are released, they must get in the choppers AKA "wrecking balls" and the one honour rule that must be obeyed is that the zombies must stay in their choppers. Now, kill, little wrecking balls.

There are two zombies:
Zombies have a 0% damage modifier, meaning they can only kill via splatters.
Zombies have full vehicle use.
Zombies must kill.

If you happen to be a poor little human, I'm afraid those flimsy looking structures built out of movable objects are your only defence, coupled with a strong pair of legs.

Humans:
Survive by using your ninja powers until the time runs out.
Don't try and kill the zombies, you also do 0% damage.

Before you get to look at all those screenshots, allow me to recap:

2 zombies start in boxes, 20 seconds later, they are released, they get in their choppers and splatter everyone.

All other players are humans, who must run around trying not to get splattered as their structures fall to the ground around them.

Screenshot time!

Okay, now the most interesting thing about this map, is the fact that the scenery is dynamic.
Remember those tranquil overview pics? Almost looked cute, huh?
Well... Look what happens:

This map uses a modified grifball court. The creator of that court says he doesn't mind people using it to make non grifball based games.
Here is a link to his map:

Here is his post I am talking about:

just so you know...
i have no problem with re-purposing any of the Grifball maps i have made as long as you DO NOT use it for Grifball or a Grifball style game variant

WafflyNumber, Dave The Rave52 and Trio Enzyme were all very helpful in making this map. I would like them to have their due credit here.
