Tennix is a single- and multiplayer tennis game from the bird's perspective. In single-player mode, the user plays against the computer AI using either the keyboard or the mouse. In multi-player mode, two players share the keyboard (or one players uses the mouse and the other one the keyboard). The game features different types of game courts (grass, clay, hard) and can also be played with a Joystick. Full-screen and windowed modes are possible. This version is the first release on CNET Download.com.
