dm_ninjaball_v1 mod for Half-Life 2

Ninjaball is a HL2 version of dodgeball, with a twist. metallic balls line the two rooms, and three energy shields seperate the two rooms. one of the shields may be deactivated by removing an energy ball from the surrounding columns. the shields can be re-activated by blasting an energy ball into the base of a column. two upper rooms are above the main two rooms, and those rooms are the player spawn points. players will find no guns in this version, but may expect to see them in future updates. no points are awarded for killing a player with a projectile, but crowbars and starting guns are still present. the only way to win at ninjaball is to come out of the game with a positive(+) score.
