It takes the form of a traditional horizontal 2D shooter (or shmup as the 'in' crowd like to say) but quickly morphs into something a little more leftfield. The player has to shoot down Sega control pads, hostile compact discs and even pink joypads that resemble Playstation controllers. Before you have time to ponder the deeper meaning of the CD format being the enemy of Sega, things suddenly become even more brilliant. Now you're involved in a boss rush with the bosses taking the form of Sega's past computers and consoles. The SG-1000 kicks things off, spewing out 8-bit sprites from games that it hosted in evil 'bullet hell' patterns. Perhaps the greatest moment however is coming up against the legendary Mega Drive which has a bit of a Power Rangers tranformation sequence moment with the Mega CD and 32X bolting themselves on for one hell of a boss. A screen-filling Saturn makes a dramatic appearance and...you know what? Words on a screen really don't do justice to what is one of the coolest things a fan of retro games will ever see.
Fast forward the below the video to 31:10 to witness the utterly bonkers brilliance.
