Fancy playing a decent Shoot 'em up, then come and check out Papi & Sohn's Space Trolls of Mahlsdorf, a feature-packed new shoot ’em up for the ZX Spectrum. Built using Jonathan Cauldwell’s Multi-Platform Arcade Game Designer (MPAGD), Bruce’s specialized Shmupkit, and as a Father and Son team, the title features a gauntlet of diverse alien invaders, plunging comets, relentless Jetmen, weapon power-ups, and a massive final boss encounter. While skilled solo pilots can technically complete the challenging campaign alone, the game was specifically engineered to fill a massive gap in the retro homebrew scene by introducing a fully integrated co-op experience.
