With the Left/Right Keys you cycle throu the heroes and get a descriptions of their skills, as well as some background information. This Screenshot was taken in my Survival Map. In my lil RPG, there are no skill descriptions, but lots of background about the character.
If someone is pressing the Down Key, the hero will have some special effects and change the color to the player who selected the hero. No other can select this hero now.
In the AoS, a new hero will be created for the player and he can start playing. In the RPG, he has to wait until all players selected a hero.
To use it in another map, I just have to copy it and set a variable for max hero number, one for max player number and save every hero typ to a variable. Oh, and editing the description :-)
Edit: Uh crap, the camers angle is wrong.. the hero should fill the whole screen :-/
