This scenario is not only an example of implimentation of actual waterfalls that span multiple levels of terrain, & look realistic, but a six player map for you & friends to play on. i built this scenario with nothing but the scenario editor that comes with the game. i didn't even hex edit it. Tell me what ya think.
The 'waterfall' is the technique that's been around for ages. Remove bridge sections using triggers blah blah blah. Multiplay map? Black forest with a lake added in the middle.
