Guerrilla War (c) 1987 SNK.

The country is struggling under the cruel domination of its evil King. The rebel guerilla leader and his comrades attempt to secretly land on shore. The King's military is waiting for them, however, and the players must fight their way inland to reach and destroy the King's palace stronghold.

In this, the pseudo-sequel to SNK's own superb "Ikari Warriors" (released two years earlier), players must once again shoot their way through a number of vertically scrolling levels, all packed with large numbers of enemy soldiers, gun emplacements and vehicles. Each level also contains a number of captured prisoners tied to wooden stakes, and these can be rescued for extra points.

The players' weapons have only a limited amount of ammunition and additional ammo/grenades must be picked up along the way. A number of gun upgrades can also be found. At various points in the game, players can also enter unoccupied enemy tanks, which provide increased firepower as well as resistance to enemy shots. Too many enemy hits, however, will eventually see the tank explode - this is proceeded by a warning flash to allow the player to exit the tank before the explosion occurs. Should the player be caught inside or near the tank when it explodes, a life is lost.

As with "Ikari Warriors", Guerrilla War features full 360 degree gameplay with attacking troops appearing from all directions. The players' on-screen counterparts are able to rotate themselves accordingly.

Released in March 1988 (even if the titlescreen says 1987).

This game is based on the Cuban revolutionary war against the Bautistas that occurred in the 1950's. The first player controls Chè Guevara and the second player controls Fidel Castro, current Cuban dictator. The storyline was changed completely for the US version, because Fidel Castro of Cuba and the United States are bitter enemies, and out of respect for the Cuban Missile Crisis.

The Japanese version of this game is called "Guevara".
