Based on the famous Rambo movie, Ikari Warriors will bring intense fighting missions and you will face many enemies and dangerous pitfalls at the same time. The content of the game revolves around the combat mission of the two main characters, Lieutenant Clark and Colonel Ralf. Your main task is to quickly pass units of enemy soldiers to reach Ikari village – where the enemy is surrounded and in danger of being destroyed.You can distinguish Clark and Ralf based on the color of the dress, Clark is blue and Ralf is red. The game is prepared with 2 players and 1 player mode. Characters of the game are allowed to move in 8 different directions and you will control the character with the top view. There are 2 main weapons for you to use: machine guns and bombs. In it, bombs will help you destroy the blockhouse and machine guns help you destroy the soldiers of the enemy.

IKARI WARRIORS is an action shooting game released by SNK in 1986. Play as Colonel RALF and Lieutenant CLARK to infiltrate enemy territory and take down an evil organization from the inside.

In addition to the two simple weapons above, you can also use two other means of fighting, tanks, and battle helicopters. The above two vehicles will help you fight the enemy more easily. The tank can neutralize the onslaught of enemies and you can quickly eliminate all the bunkers there along the way. Combat helicopters have the same combat capabilities as tanks but are equipped with two offensive weapons, spread guns, and rockets.

In addition, it can fly over rivers, something tanks cannot do. However, the fuel and ammunition on these two vehicles are limited. To continue using, you need to collect fuel and ammunition (can be collected after destroying the enemy blockhouse). When the fuel runs out, the two vehicles can easily be destroyed. Therefore, you need to quickly get out of helicopters or tanks to avoid being blown along with them. In general, the two vehicles above have their own advantages, but you need to use them reasonably to complete the task in a short time.Besides, the number of enemies will increase gradually in stages, enemies also own tanks and helicopters like you. From there, you need to pay close attention and avoid the attacks from the above vehicles.

One of the outstanding features of the game is that it prepares a firewall system at the bottom of the screen to motivate players during combat, limiting the phenomenon of players moving too slowly.

Ikari Warriors is a vertically scrolling, run & gunshoot 'em uparcade game developed by SNK, published in North America and Europe by Tradewest, and released in 1986. Originally titled Ikari (怒, 'Fury') in Japan, Ikari Warriors was SNK's first major breakthrough US release. The game was released at the time when there were many Commandoclones on the market. What distinguished Ikari Warriors were rotary joysticks and a two-player mode.^[6]

The player characters in Ikari Warriors are Colonel Ralf and Second Lieutenant Clark of the later King of Fighters series (known outside Japan as Paul and Vince in the Ikari series) battling through hordes of enemies. According to designer Keiko Iju, the game was inspired by the popular Rambo films and takes its name from the Japanese title of Rambo: First Blood Part II (Rambo: Ikari no Dasshutsu or 'The Furious Escape').^{[citation needed]} Ralf and Clark also make an appearance as playable characters in Metal Slug 6 and Metal Slug 7, as well as the King of Fighters series. Ralf and Clark were also featured as cameos in Super Smash Bros. Ultimate as background characters in the King Of Fighters Stadium stage as well as the both of them sharing a Spirit.

Gameplay[edit]

The player takes the role of commando-like warriors named Ralf (red) and Clark (blue), who must try to reach the village of Ikari. Enemy units attempting to kill the player include tanks, enemy soldiers and helicopters. A number of power-ups along the way help the player achieve victory.

Players must proceed from the bottom of the screen upwards, towards the village of Ikari. Trying to prevent them from reaching the village are enemy soldiers and other units. Along the way, players may commandeer enemy tanks and helicopters (NES version) to help fight their way through the enemy personnel. The tanks are immune to enemy bullets, but have a limited supply of fuel and will sustain damage when it runs out or the tank is caught in an explosion, taking the player with it unless he can exit the tank and get clear before it blows up. The helicopters have two different weapons, a spread gun and a cannon, and may fly over water.

Rotating the joystick changes the direction the character faced independent of the direction the character was moving, as controlled by pushing the joystick. This gives the player freedom to attack or walk in eight different directions. No shot is fired from directly in front of the player; the warrior uses the machine gun in his right hand, and throws grenades with his left. If a player character takes too long moving up screen, the computer starts using 'call for fire'. A red spot appears below him; this is tracking fire to speed up the game.

Hardware[edit]

Ikari Warriors is the first popular video game to have used rotary joysticks, which can be rotated in addition to being pushed in eight directions. The less successful TNK III, released in 1985 and also from SNK, is the first to have used such joysticks.^{[7][8][9][10]} The system also features two buttons: one for the standard gun and another for lobbing grenades. It is one of the few games at the time to allow two-player cooperative side-by-side gameplay, and to use vehicles. The game cabinet is a standard upright model.

Ikari Warriorsprinted circuit boards (PCBs) were manufactured in two different versions: SNK pinout and JAMMA pinout. Most SNK-pinout units were put into Ikari Warriors cabinets, while most JAMMA-pinout units were supplied as conversion kits. The SNK-pinout boards have a 22/44-pin edge connectors. The JAMMA-pinout PCBs have a 28/56-pin edge connectors. Both types consist of a stack of three boards, with interconnects.

Ikari Warriors uses SNK's model LS-30 joysticks, which contain a 12-way rotary switch box. The joysticks are connected to the PCB via auxiliary wiring harnesses.

Regional differences[edit]

The game is known simply as Ikari in Japan and Ikari Warriors in the United States and Europe. In addition to changing the names of the main characters from Ralf and Clark to Paul and Vince, the military commander the player rescues at the end of the game is named General Kawasaki in the Japanese version (named after SNK's founder Eikichi Kawasaki) and Colonel Cook in the US/Euro version (named after Tradewest's founder Leland Cook). General Kawasaki's name was unchanged in the NES version. The enemies in the game were actually Neo-Nazis, as evidenced by the presence of a swastika at the middle of the final room.

Ports[edit]

Ikari Warriors was ported to the Nintendo Entertainment System, IBM PC, Apple II, Atari ST, Atari 2600, Atari 7800, Amiga, Commodore 64, ZX Spectrum, and Amstrad CPC. The MSX port and conversions for 16-bit machines were released in 1987. The PC and Commodore 64 ports were developed by Quicksilver Software. In 1989, a second C64 version was released in the UK by Elite Software. The NES version was developed by Micronics. Both the Atari 2600 and Atari 7800 ports were released in 1990 as one of the final published games for those systems. The game was also included on the SNK 40th Anniversary Collection for the Nintendo Switch and PlayStation 4.

Reception[edit]

In 1996, Next Generation listed the arcade version of Ikari Warriors as number 61 on their 'Top 100 Games of All Time', lauding the innovative joysticks, play balance, and power-ups which offer an invigorating boost to the player character's capabilities without taking away the game's challenge.^[6]

Computer and Video Games enthusiastically reviewed the 'classy' Amstrad personal computer conversion, calling the graphics 'simply brilliant' and the gameplay 'awesomely addictive'. They said that players 'won't see better .. probably for quite a while' because 'the Amstrad graphics are as close as dammit to the arcade machine and the playability goes off the C+VG scale'.^[4]

The PC version of the game received 4 out of 5 stars in Dragon.^[13]

Legacy[edit]

Ikari Warriors spawned the sequels Victory Road (1986) and Ikari III: The Rescue (1989).

SNK released an Ikari Warriors clone in 1987 called Guerrilla War (known as Guevara in Japan). The game features communist fighters Che Guevara and Fidel Castro as its heroes.
