When running GMA Tank Commander for the first time, you will be asked for your registration name and product key. Make sure you have received the information from your vendor or from GMA directly.

Before you purchase the game, you may run a limited version of GMA Tank Commander. You will be able to play the first mission, and if you decide you like the game, you can purchase a product key that you can enter later to access the full version!

To get started playing GMA Tank Commander, you may read the GMA Tank Commander help in text format from the "Read Manual in Text Format "selection in the GMA Tank Commander Start-up sub-menu. You may also access the Menus by pressing F1, or access the help system by pressing Control-F1 while in the game.

You will require a new product key with version 1.2 if you are upgrading from version 1.0. There is no charge for the upgrade, but you will need to use the Ordering Wizard to request a key replacement.
