Star Defense Operation (SDO), the latest release from developer xevimet4l, is now available for the Amstrad CPC, bringing a dose of high-octane, vertical-scrolling arcade action to this 8-bit system. SDO is designed specifically for the CPC’s 4 MHz hardware to hopefully deliver a fast, smooth vertical shoot-’em-up experience, even when the screen is swarmed by alien invaders. Players can expect a polished "arcade flow," complete with parallax starfields that create a genuine sense of depth as you blast through the void.
