Originating in the arcades, Spy Hunter is a driving action game played from an overhead point of view. Your car is equipped with machine guns to help you get past the numerous enemies out on the road (be careful not to shoot any civilians, though!) Occasionally you will come across a weapons van, and if you drive into the back of the van your car becomes equipped with a second weapon (such as smoke screen, oil slick, or missiles). At several points the road splits and you can enter a boathouse which transforms your car into a boat temporarily. If you drive far enough the seasons change as well (watch out for icy conditions during winter!). The enemy cars will do anything to stop you, including running you off the road, firing guns from the back of a limo, or dropping bombs from a helicopter.
Xenophobe is a 1987 arcade game developed and published by Bally Midway. Starbases, moons, ships, and space cities are infested with aliens, and the players have to kill the aliens before each is completely overrun. Xenophobe can be played by up to three players, and the goal of each level is to defeat all the aliens before time runs out. Some rooms routinely display the percentage of alien infection and time remaining until self-destruct when the level ends (but a nearby button can temporarily deactivate the count-down). Levels may contain more than one floor, and players use elevators (and sometimes holes in the floor) to move between floors to defeat all of the aliens. Players can also pick up more powerful weapons and other items to help in their eradication of the aliens.
