Slingshot

Slingshot is a gravity‐based TBS, written in Python by Jonathan Musther and Bart Mak using Pygame. The latest version is 0.8.1p, released in 2007 under GNU General Public License 2 or later.

Gameplay
Version 0.8.1p only supports a local two-player mode.

At the start of a level, two ships and a few planets between them are placed randomly in the rectangular space.

At their turn, a player chooses the power level and direction to shoot at using arrows, and presses spacebar to shoot.

The projectile is strongly affected by the planets’ gravity, so it is not always easy to hit the other ship.

The projectiles leave faint permanent traces, so the players can avoid shooting in the same direction (but they do not indicate the power).

The power used during the level is substracted from the winning score.

The game’s homepage was defunct in the middle of 2009.
