Nightfall

Nightfall is a cancelled PC game by Maxis South. It was to be a 3D sci-fi vehicle combat game.

Plot
You would play as a technician in charge of terraforming a planet fit for human life. The local aliens are not too happy at your colonisation and fight back. To complicate matters, other terraforming terms want to wipe you out to take all the credit.

Gameplay
This planet is interesting in that the weather can change at anytime. As you and the other teams duke it out, the environment will be terraformed with the attacks.

Multiplayer supported up to two players via online internet and eight players via LAN.

Cancellation
Nightfall was cancelled due to an unacceptable framerate and lackluster graphics.
