SDO - A fast vertical shoot’em up for the Amstrad CPC by Xevimet4l

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.

Here's the latest from the website "SDO is a vertical shooter made for Amstrad CPC. It’s built around tight controls, readable Mode 0 graphics, and an arcade-style loop, high scores, and a proper “one more go” rhythm. Choose joystick or keyboard, remap keys if you like, then dive in — the invasion won’t wait. Who it’s for ? For retro players, CPC owners, and anyone who likes short sessions, clear feedback, and old-school challenge without pretending to be a modern AAA game."
