It isn't exactly what you had in mind.
The way is it planned to work (I don't have a ton of work done on it) is that the Duck Factory breaks down, releasing rubber ducks everywhere. One team (The Ducksters) can find any duck they want, click it, and it will disappear, also turning them into a duck. This way you might notice if a duck is missing.
Every few minutes, the ducks would get a message saying they have to move in the next 20 seconds. If they don't get far enough away from their original location they will die.
The round is won when the ducks live for a set amount of time. If all the ducks die, they lose.
Ducks will have 1hp, so they will die instantly if hit. Although, if you attack a rubber duck, you will take damage. This means you can't shoot everything you see.
Don't expect this to be released any time soon. I am already working on multiple projects.
