We turn our attention to the ZX Spectrum now for some retro gaming goodness, as if you love playing Arcade games whereby rescuing hostages is the aim of the game, then you might like playing ' Agent Blue' developed by José Silva, Jaime Grilo and IK (Artur); a typical arcade game for the Spectrum 48K (no music) / 128K (with AY music) made using AGDX (a modified version of Arcade Game Designer 4.7) and AGDMusicizer II.
