XBATTLE4, GAMES, Multi-user battle strategy game under X Xbattle is a concurrent multi-player battle strategy game that captures the dynamics of a wide range of military situations. The game board is a matrix of game squares (or hexagons- see "-hex" option below) which can be occupied by troops of various colors or shades. The number of troops in a square is indicated by the size of a colored troop square (or circle, with "-hex") within the game square. The troops are commanded by clicking the mouse near the edge of the square in the direction that the movement is to take place. The command will be acknowledged by the appearance of a command vector, and thereafter, in each update cycle, a certain proportion of the troops will move from the source square to the destination square until the source square is exhausted. Command vectors can be set in several directions at once, in which case the movement is divided evenly between the vector directions, and the command remains active until cancelled. Thus a trail of squares can be set up as a supply line that will deliver troops steadily at its endpoint. The command vector remains active even if the number of troops in that square is zero, although the command vector will then be displayed at half length. The game is concurrent, so that commands are given continuously by all players without waiting for turns. Different combinations of options create radically different games.
