from the aliens, and although one can fail these missions and still progress through the game, doing so will result in significant human casualties. The use of vehicles is a key aspect of this game. Vehicles provide significant protection from alien attacks and allow the player to travel at a far greater speed than on foot. Adam can still fire most weapons from within a vehicle, although many vehicles are equipped with powerful weapons of their own. Vehicles take damage independently of Adam and can be repaired with health pickups spawned by defeating larger aliens. Specific vehicles are often required to advance - for example, boats allow travel over bodies of water, while planes and helicopters allow travel through the air. Each vehicle has a unique combination of top speed, armor and fuel capacity, inviting players to consider their options carefully. Vehicles range from mundane civilian forms of transport to powerful military hardware - the player will pilot tanks, armored cars and aircraft as frequently as cars, trucks and motorcycles. In addition, the Alpha I (the ship the player uses to travel through time) becomes a powerful armored hovercraft during boss battles and for the entirety of the Comet level. There are many buildings in each stage which can be entered on foot, many of which are essential to talk to plot characters and acquire necessary items. Buildings also contain health pickups, new weapons other than the standard pistol are a machine gun, shotgun, rifle and rocket launcher that each use different types of ammunition. The buildings also have Ammunition pickups and fuel cans (of which one will refuel a vehicle once). With thorough exploration, rarer items can be found including alien artifacts and 'weapon crystals', three of which combine to form a technologically advanced powerful laser weapon unique to that level. The eventual goal of each level is to destroy the Shield Generator to remove the shield that surrounds the region. To do this, the player must first destroy a number of Alien Processors, which act as sub-bosses. Defeating an Alien Processor opens a gateway to the next area and allows the player to save their progress. Once the Shield Generator itself has been destroyed, the player immediately faces that level's boss. Once the boss is defeated, the player travels forward in time and to the next level.
