Sonic Boom1987

A helicopter shoot-'em-up developed by Sega. The Arcade version made use of Sega's 3D super scaler technology to create city environments where the buildings would appear to have depth. The subsequent home versions sadly lacked this feature.

It's a nightmare, but it's true! Research shows that we are the actual aliens on Earth, and the ruthless Xevions are the original inhabitants. Now the Xevions want Earth back -- minus humans! Their invasion forces are fierce -- the land is crawling with deadly Domogram Rovers; the sky is black with Toroid Patrol Fleets and Zoshi Death Squads. Our puny weapons offer no defense. Earth's only hope is our powerful new Solvalou Fighter Plane. Its pilot will have a single mission: Penetrate the enemy ranks and destroy the Xevious Mother Ship. The mission is dangerous. We can't guarantee success. But at this point, it's do or die! One small problem. We still need a pilot. Any volunteers?

Mission: Code Name River Raid. Jet down the river. Break the enemy blockade and blast the bridges to halt enemy troop advances. Terrain: Code Name River of No Return. An ever-changing, ever-challenging waterway. Expect huge islands, narrow channels and treacherous bays crawling with enemy choppers, tankers and jets. Weaponry: Code Name StratoStrafer.

Overhead run'n gun-style shoot-'em-up. You play as jeep driver and gunner rescuing POWs. More commonly known as Jackal outside the US.

A helicopter themed shoot 'em up action game from a birds eye view. Developed by Toaplan, it is the successor to their first STG Tiger-Heli, and features similar gameplay.

The players are members of a covert counter-terrorist team of mercenaries known as the "Wolf Force". The aim of the game was to rescue the former President from rebels in the fictional African country of Zutula, which bears resemblance to the apartheid regime in South Africa. The game has six main levels, plus the final level where your mission is to rescue the former U.S. president from the Hercules Transport. The game's arsenal include real-world machine guns, shot guns, flame throwers, and grenade launchers. Several missions even have pilotable vehicles available.

Shock Troopers is a 1-2 player game where players select one of eight characters to play as. Each character has their own attack. Players also have to choose one of three routes to take. The object of the game is to go toward the end of the level and defeat the end-of-level boss, which is usually a huge vehicle. Crates that are scattered throughout the levels can be broken into to reveal new weapons and power-ups. There is a team mode where players have to select three characters. The characters can be switched on-the-fly during gameplay, which is useful if one of them is badly injured. Players can use the other teammates until life-ups can be found.

Time Pilot is a multi-directional scrolling shooter and free-roaming aerial combat arcade game designed by Yoshiki Okamoto, released by Konami in 1982, and distributed in the United States by Centuri. Debuting in the golden age of video arcade games, it is a time travel themed game that allowed the player's plane to freely move across open air space that can scroll indefinitely in all directions. The Killer List of Videogames included Time Pilot in its list of top 100 arcade games of all time. The player assumes the role of a pilot of a futuristic fighter jet, trying to rescue fellow pilots trapped in different time eras. The player must fight off hordes of enemy craft and defeat the mother ship (or "boss") present in every level. The background moves in the opposite direction to the player's plane, rather than the other way around; the player's plane always remains in the center.
