Your mission, as usual in a war game, is to attack and destroy the enemy. You move forward in your little red tank by destroying the blocks in your path. If your tank moves onto a green zone it will start to slip and use more fuel.
It is a good idea to move round to the side or behind the enemy gun position so that it can not shoot at you and it is easier to destroy.
An alarm will sound when you are running out of fuel, but if you manage to re-fill you can get through enemy lines and pass under the triumphal arch - and get onto the next screen.
In order to re-fuel your tank you must move on top of the fuel tank - the fuel gauge will then indicate full.
In scene two enemy aircraft make a surprise attack. You must shoot them down whilst avoiding missiles from planes zig-zagging above you. This time if you move onto the orange zone, you slip and lose petrol.
You add to your score by moving forward, destroying blocks and gun positions and shooting down aircraft. You lose one of your three tanks by colliding with a block, by being hit by a shell or missile, or by running out of fuel.
Strategy X is not one of the best battlefield games around. It has unrealistic graphics, although I like the way the tank moves along, but at the price who can complain!
