Haxball

HaxBall is a top-down online multiplayer game played between two teams. It
is played on fields of various types with a goal on two sides. Each player is
represented by a circle that can be moved around to push a white object that
moves like a ball or a puck into the opposing goal by guiding it into the
right direction. Players can also hinder each other by blocking the way. Next
to the four arrow keys for movement an additional key is used to kick the
object when it is close enough, based on the position of the object relative
to the player. This movement can be combined into teamwork to pass the ball
and get past opponents to score.

Players assemble in a central lobby where games can be created or joined. The
hosting players can choose the type of stadium and the rules such as a time or
score limit. Before starting a game players choose a side but it is also
possible to join mid-game. Teams do not necessarily need to have equal
numbers. Next to the regular game mechanics there are servers where movement
is changed, for instance to carry more momentum, or where the object bounces
off the walls as in a game of ice-hockey. Custom maps can be used and these
are created through an unofficial editor. There is a chat window at the bottom
of the screen during matches to talk to other players. Through the logo the
game appears to suggest it resembles a game of football (soccer).
