It's an all-shooting episode of Segaiden with the Master System's second light gun game. (Or third, if you take a doggedly literal view on the names on cartridge labels and count Marksman Shooting / Trap Shooting as two separate games. I bet you probably still put an apostrophe in Ys, too, don't you?) That's followed by the first of December 1986's Commando / Front Line clones, Rambo: First Blood Part II. OK, that's not fair to Rambo. It doesn't want to be Front Line (who does?) but rather Ikari Warriors, and it has the cooperative play to prove it. Although it certainly is fussier about its secret continue codes.
