Battlezone is a critically acclaimed remake (for Microsoft Windows) of an arcade game of the same name. It was released by Activision in 1998. Aside from the name and presence of tanks, this game bears little resemblance to the original. Activision remade it into a hybrid of a tank simulation game, a first-person shooter and a real-time strategy game. Battlezone is played like any other real time strategy, but the main difference is that in Battlezone the player is controlling everything on the battlefield from the first person view.
The one and only resource in Battlezone is bio-metal scrap which is used to produce new units and construct new buildings. Building and directing units is done via interface either by selecting onscreen object with mouse or by using number keys on keyboard. Starting with a bio-metal recycler (the most basic construction unit), the player constructs vehicles to scavenge scraps of bio-metal, build base defenses, and construct new base vehicles capable of building more advanced structures and vehicles.
