Vampire! Vampire!

Take command of a Frigate as you defend your convoy against anti-ship missiles, or play with a friend on the same keyboard in the two player Cruiser. Can you make it through all 3 stages? Use the radar to track and identify targets. Fire the missiles while tracking the target, but be sure not to target the wrong contact. 

Controls:

Frigate:

A and D to turn Tracking Radar (Fire Control Radar)

W to fire missile

S to fire the gun

Cruiser:

Left and Right Arrows to turn second Tracking Radar

Up Arrow to fire missile

Down Arrow to fire the gun

Scoring: 

+25 for each basic missile that misses or is intercepted

+40 for each sprinting missile that misses or is intercepted

+200 for each Bomber shot down

+400 points for each surviving ship at the end of the stage

-500 points for shooting down a civilian airliner

-10 points for each missile fired

-5 points for every time the gun is fired

Gameplay:

The missiles are meant to emulate older semi-active radar missiles. The radar must be held on the desired target for the missile to track. Painting multiple targets with the radar may result in the missile going for the wrong target or being unable to track. The missiles do not home in on their targets, but rely on flying a constant heading until they hit something. It is important to determine which missiles are threats as shoot them down first. The bomber will close in on the convoy and fire two missiles then turn away. It helps to spot them and shoot them down before they get too close. At later stages, the sprinting missiles can appear. Sprinting missiles increase their speed when they get close to the convoy and fire decoys to confuse your missiles. Shooting them down early or hitting them at close range with the gun can help.
