Jump in and take command in a fight that spans six exotic worlds with diverse environments - from steaming, swampy jungles crawling with deadly creatures to rocky wastelands strewn with boiling lava pits to ruined cities half-buried in nuclear snow. Players start by building a base from which they command a force of armored vehicles, infantry, and aircraft through a series of exploratory, offensive and defensive missions. Gamers will drive a variety of tanks and walkers, pilot the scout ships, and even jump out and fight an evil and challenging alien enemy on foot. Each side will choose from an arsenal of powerful weapons including guided missiles, mortars, mines and bazookas. This revolutionary game is the sequel to 1998's Action Game of the Year (Computer Gaming World). Complete Control Over the Battlefield!
The last known cumulative "official" unofficial patch (maintained by one of the game's authors) for the classic BattleZone II Combat Commander that has an impressive list of changes (including compatibility with the newer Windows OSes and performance/stability upgrades among many). Definitely not compatible with the remaster, if you even need to ask. Considered "Public Beta" but it works all dandy.
