Almost certainly there exists someone who has played Cabal (developed by TAD, published by Taito) in the 80's or 90's and thought they were playing the future. Unfortunately, the surprising charm and fun game play aren't what ended up carrying on into today, more so the generic military shooter simulation.
I was genuinely enjoying my time playing Cabal and it really only requires six inputs: four directional buttons which controls both aiming and moving, one for shooting, and one for grenades. Initially it felt a bit odd having aim and move be controlled with the set of keys but when you start shooting your character stands still and the targeting reticule removes surprisingly smooth.
The main objective of the game is to shoot your way through a set of four levels and fight a large boss at the end. In the first world, it's in the form of a giant explosive launching aircraft and in the second a submarine firing off volleys of bullets. Several different kinds of enemies are slowly introduced including tanks, units that throw grenades, units that can avoid your bullets by dodging, helicopters with machine guns, and even airplanes that occasionally making bombing runs on your position.
Based on the game's presentation it would really benefit from being in an arcade cabinet. The "from the back" view is perfect for a cabinet's enclosed, tilted screen; the two player option seems like a lot of fun; the controls make sense for a joystick and two buttons; and there's definitely enough flashing pixels for it to fit in right next to a Pac-Man machine or something similar.
One thing I do want to mention is the game is actually rather difficult and after failing to defeat the submarine boss at the end of the second set of levels about 10 times I decided to call it quits. The boss' health resets when you die so you lose all of your progress on it (at least in the single player mode). However, I understand that the difficulty is because they want the player to have to spend more coins but even with that context it's still frustrating.
Feel free to try the game for yourself on the Archive.org's Internet Arcade. Since the archive doesn't list controls here they are for Player 1:
