Metal Slug 4 / 4K PS2 emulator PCSX2 / RTX 2080ti
5Metal Slug 4[b] is a run and gun video game for the Neo-Geo console/arcade platform created by Mega Enterprise along with Noise Factory. It was released in 2002 for the Neo-Geo MVS arcade platform, and is the fourth game in the Metal Slug series. Two years later, Playmore published Metal Slug 4. This was also the only Metal Slug game that was produced during SNK's bankruptcy, until its sequel released after SNK was "resurrected" as SNK Playmore. It was developed via reverse engineering the Neo Geo cartridge of Metal Slug X.
Metal Slug 4 retains the same game-play as previous titles, with the addition of some new enemies, bosses, weapons, several new vehicles and a new bonus combo system. It was later ported to Microsoft Xbox (not compatible with Xbox 360) and Sony PlayStation 2 as a stand-alone game in Japan and Europe, and along with Metal Slug 5 as a compilation in North America and South Korea. Nintendo Switch version was released in 2018.[2][3]
