Spy Quest 1 - MISSION: SPECTRUM -Windows-

 Remembering Steven Don´s Misson: Spectrum game

 

Steven Don: "Mission SPECTRUM is my tribute to the older text parser adventure 
games as made in the 1980s by Sierra. Not written in actual Sierra AGI, 
but with the same kind of blocky low-res style of artwork in all the 16 
glorious EGA colours".

You play as Agent N of the HCA (Highly Clandestine Agency) and are on a mission to infiltrate Spectrum Enterprises' corporate HQ to find out what nefarious scheme they are about to unleash on an unsuspecting world. Or have they perhaps already done so?
