The Ocean Battle is one of those exceptional games which make you wonder why they are freeware. The game offers an amazing simulation of an air battle during war-time and completely immerses you in its scenario. The 3D environment and models are extremely well made and the gameplay is engaging.
The game has three missions.
Mission 1 involves dogfights. Once you have gotten rid of your airborne enemies you can progress to Mission 2. In Mission 2 your aim is to destroy ground obstacles and avoid getting hit, so that you can move on to ...Mission 3, in which you have to destroy the enemies main Battle Ship.
What's the catch I hear you say... Well it's an obstacle rather than a catch, the game menu and intro are in Japanese.
However, this game is too good to be missed for such a minor reason. It is very playable even if you don't speak a word of Japanese. In order to help you out here is a list of the controls:
Aircraft Control----------------Arrow Keys
Speed Increase/Decrease Keys-------A/Z keys
Target Acquisition-----------------Arrow-icon at the top of the screen.
You need to have DirectX8 installed in order to play this game.
