This scenario will only take five minutes of your time, but it is worth playing to the end! It is a simple concept about feeding ducks, but the execution is actually really impressive. I can only guess that the author must have used Lua, because there are some pretty cool things done here that I've never seen done in the Marathon engine before.

Play this if you're looking for a fun five minute distraction, or if you're a mapmaker and want to see some nifty Lua effects.
