I think it would be cool to have a new map that takes place in a zoo. The premise could be that a crazy rich guy hired mercenaries, hunter, etc. to capture various animals from shear, and put them in his own zoo/wildlife reserve. The people hired to take the wildlife into the zoo find a huge egg and decide to take it as well. When they arrive and put the egg in an exhibit it hatches threatening nearby inhabitants as well as the rich guys Zoo.
Hunter Win: You get some extra help from the people the rich guy hired or are provided with something new or better equipment from the rich guy.
Monster Win:Not sure. Maybe increased armor?
Let me know what you think or have an idea for the map or its bonuses
