Speedy is a map that allows Player 1 to modify the speed of all units on the entire map.
Type Speed+ in chat to increase speed for all units by 0.5
Type Speed- in chat to decrease speed for all units by 0.5
Whenever speeds are increased by 0.5, range and LOS of all units are increased by 1.0
This also applies for decreasing values.
Higher speeds help units that are usually slower to catch up (like siege weapons) while lower speeds help bringing out advantages of units that are normally faster (like cavalry).
The map is also included in an update of my "Modified RMS Pack" I uploaded recently.
Have Fun!
