Zeewolf

With a similar gameplay as the isometric Desert Strike, _Zeewolf_ offers
arcadesque helicopter combat in a 3D surrounding. Despite its mainly action-
oriented gameplay, the 32 levels often involve support, transport and rescue
missions – dropping or refueling friendly units in the combat zone, for
example. In exchange, other units serve you as rearming points or help you
fighting the enemy.

The order of the levels can be chosen freely and the game may be played with
joystick or – a little unusual – with the mouse. The game uses a third-person
engine, looking at the helicopter from the side and displaying a certain
amount of landmass in a square around it.
