It's the SEGA Mark III's birthday again. You may want to try Astro Climber which I made last year to celebrate.

Razing Core for the Sega Master System (Bad Computer/2026). New vertical shmup for this classic 8-bit console. With 7 stages, primary, secondary and Core weapons, large bosses and more, it offers great gameplay and reminds me of the Aleste series. Physical release is planned for 2027. badcomputer0.itch.io/razing-… #gamedev #Sega #8bit

Just grabbed Razing core by @badcomputer0 Awesome shmup for the SMS! I am completely blown away by what indie devs have squeezed out of the Master System.

Thanks for the review Inglebard, I'm glad you liked it!

More Master System? YES! Check out my review of Razing Core, a new vertically scrolling shooter (or SHMUP) for the system from Bad Computer. Is it worth playing? Watch the review for the answer! Link: youtu.be/a6O_G5IRHgY #sega #sms #mastersystem #shmup

I certainly wanted III too but a good opportunity never came up. I don't collect as actively these days but it's expensive now.

I was certain I had Gley Lancer in storage somewhere but I couldn't find it. But I still found lots of old friends instead 🫡
