In StarCraft: Ghost, players take the role of Nova, a lethal Ghost operative trained in the arts of espionage and tactical combat. Twenty years of ruthless physical conditioning and techno-psychological instruction have transformed Nova into a being of terrifying potential. As she progresses through a series of story-driven missions, Nova is required to engage in dangerous infiltration operations and deadly planetary battles. To complete Nova's mission objectives, players must execute intelligent tactical decisions while mastering an advanced arsenal of sophisticated weaponry and Nova's own psionic abilities.   In addition to utilizing Nova's special abilities to carry out covert operations, players can call in offsite support ranging from ComSat scanner sweeps to all-out tactical nuclear strikes. As they advance through the game, players will have the ability to operate a number of vehicles, unique to the StarCraft universe, including Goliath Combat Walkers, Vulture Hover Cycles, and Arclite Siege Tanks. Also, to aid them in combat, players can go into a zoomed-in sniper mode from anywhere in any level, using Nova's modified C-20A canister rifle.   StarCraft: Ghost features highly stylized character models, over-the-top special effects, and immersive 3D environments that reward creative exploration. The game's deeply evolving story line takes full advantage of Blizzard's StarCraft universe, so Nova will encounter locations and enemies both new and familiar-many of which will be seen in full scale for the first time.
