Scorched earth
A scorched-earth policy is a military strategy that aims to destroy anything that might be useful to the enemy while it is advancing through or withdrawing from a location. Any assets that could be used by the enemy may be targeted, for example food sources, water supplies, transportation, communications, industrial resources, and even the locale's people themselves.
Scorched Earth (video game)
There have also been numerous clones made (and still being made) such as "Atomic Tanks", "Nasty Armoured Tanks of War", "xscorch" (Open Source clone), "Scorched 3D", which attempt to modernize the gameplay and graphics, and others such as "Charred Dirt" that take a different approach by using a unique graphical style. In 1999 a clone written in Java was released called "Scorched Earth 2000" which runs from a web browser and supported online multiplayer games. There are also several variants, such as "WarheadsSE" in which the players fire missiles between planets, with the trajectories curving as missiles pass through gravitational fields.
