Squaresoft usually makes people think of RPGs, but they also made a superb shmup called Einhänder for the Sony Playstation. This artwork is simple and is from the Japanese version of the game released in 1997. It’s also seen as the title screen artwork. The US version has a 3D rendered ship.
Basically, you get the joy of Square production values from the 90s combined with a fun and unique shootemup. In the first level of Einhänder they have you flying through a futuristic Blade Runner-esque city, even smashing through neon signs. The graphics are 2.5D, that of being 3D graphics in locked 2 dimensional planes.
