Four members of the elite Blast Corps face their most perilous operation yet: two nuclear missiles have started to leak while en route to a safe detonation site. The carrier supporting them has suffered heavy damage, and in order to reach its destination as quickly as possible, it has been programmed to follow the most direct path through populated areas. Your goal is to use every vehicle at your disposal to clear a path for the carrier so it makes it through unscathed. The slightest impact will have catastrophic results, so you need to work fast by demolishing buildings and removing any potential obstacles. You must also be on the lookout for six hidden scientists who can disarm the weapons.
Fifteen vehicles are at your disposal, some of which are needed simply to reach others on a particular stage. The "Ramdozer" is designed similarly to a bulldozer, and the "Backlash" is modeled after a dump truck. The "Skyfall" resembles a dune buggy, while the "Thunderfist" is a large robot with an enormous hand for bashing. The "Cyclone Suit" is used to tumble into structures, the "J-Bomb" is a flying robot that stomps on buildings, and the "Ballista" is a futuristic cycle with twin missile launchers. There's also the "Sideswipe," a truck with two powerful panels on either side to crush objects. More traditional offerings include a van, police car, train, and boat.
Players will be able to unlock 57 levels from a 3D map of the world. In addition to completing the main carrier missions, there are also four medals (platinum, gold, silver, and bronze) to earn by finding communication points, destroying all buildings, rescuing survivors, locating RDUs, and finishing levels within certain time limits. At the end of each stage, players will receive score breakdown and ranking. They can then start a new level or revisit a cleared stage to improve their performance. While accumulated medals are saved directly to cartridge, a Controller Pak with at least 14 free pages is needed to store additional statistics or save files. Blast Corps is developer Rare's second release on Nintendo 64, after Killer Instinct: Gold.
