The closed beta is said to include developer commentaries, experimental gameplay, and a system of reporting bugs easily and effieciently.
The Closed Beta will NOT include the level up system, according to the project director. However, once the level up systm is implemented in a later release, closed beta testers will have the opportunity to obtain a special logo next to their name to indicate that they helped with the game design process. Other rewards such as a higher starting level were mentioned, but not confirmed.
The Team's need for a larger group of team members with good skills was highlighted after the game's director, Joe Cenatiempo (Jackal110369 on ModDB) stated that the game's release date of May 2008 WILL be pushed back if no new modding talent is acquired. Desperation was evident in his voice as he said that the team needed the Moding community's help.
It is sad that such an outstanding premise for a game, which has never been attempted on ModDB, might be shot down due to lack of participation on the Modding Community's part. So get out there, unemployed modders! Get the hell out there and help him out! Don't you want to be plowing through the mud with a football in your hand in May 2008? I know I sure as hell do.
