Overrun!

Overrun! offers meticulous simulation of late twentieth-century squad-level action in European and Middle Eastern terrain. Players command a battalion of infantry, armor, artillery, and helicopters on behalf of Arab states, Iran, Israel, NATO, and the Warsaw Pact. The bulk of scenarios are speculative and near-future (including an Iranian invasion of Kuwait), but one historic war is presented, the 1973 Arab-Israeli "October War." A single-player campaign of randomly generated maps starts you with a core force which you will hopefully retain and expand with each victory.

SSI builds on its Panzer Strike engine with this release. Each unit has several static attributes, from size to morale, and a changing state based on orders and circumstance which determine its combat effectiveness from moment to moment. Weapons -- and there are dozens -- are carefully detailed with six characteristics of their own. Vehicle armor is distinguished by location, so facing plays an important role, too. The manual gives a thorough explanation of the mechanics, including formulas, plus a nineteen-page supplement of tables.
