Underwater Tag? :P
(Take a look at Underwater Hunt, one of my maps. To get a good sample of a underwater scene.)
- You are murlocs or something like that. (Or naga.)
- You have to run away from the big bad seamonsters. xD
- Underwater scene would just look uber! =:D
Just combine them to make it the most awesome tag ever. Make a map where a torpedo trys to kill underwater ghosts. However as a ghost you must defeat the the torpedo by summoning suicide chickens.
