Halo Zeroto is an action game released in 2005 by Dobermann Software. The game was released for PC (Windows).

Halo Zero is a platform game with aesthetics and gameplay referring to the iconic slot machines. The title, of course, refers to the Halo series, but to a small extent uses the solutions of the popular series. The plot takes place during the battle of Reach - a fictional planet where, playing the role of John-117 (known to fans of the series more broadly as the Master Chief), we fight our way through the hordes of Convenants - a sensitive race of aliens. The goal of the game is to break through the Pelican aircraft, thanks to which we will escape from the planet full of Convenants.

The game can be played in single and multiplayer modes, although in multiplayer it is not easy to find a companion to play. There are 5 levels of difficulty with the most difficult - mythical - available only after passing the game to the previous four. With the help of arrows we direct our character, while with the mouse we can move the visible screen. The mouse buttons are responsible for shooting and using grenades. Other functions can be assigned to other keys according to your preferences.
