Swedish developer Avalanche Studios' first in-house development project is a 3D action-adventure starring a U.S. operative named Rico Rodriguez. Just Cause has Rodriguez attempting to overthrow a fictitious South American island's regime by instigating a revolution. Players will accomplish this by working with citizens, political factions, rebels, and even drug cartels in a series of explosive operations. In the tradition of games like Grand Theft Auto: San Andreas, Just Cause features a free form world with an estimated 250,000 acres of territory to traverse by plane, car, boat, or in some cases, parachute. Since the island of San Esperito is filled with cities, towns, resorts, jungles, and mountains, players can acquire more than 100 vehicles throughout their tumultuous stay. The main storyline includes over 20 missions with objectives that can be accomplished by any number of means. Hundreds of side and bonus missions are also available for fun or profit, with stunt challenges like parasailing, vehicle leaping, or skydiving part of the itinerary for tropical thrill-seekers.
