Covert Action is a surprisingly complex spy game, comprised of several minigames in between various travel screens and infomation screens. if you can bear with the control scheme (it is QUITE archaic) the game is great fun and while the formula is similar from case to case, it's still potentially fun for hours, once you get the hang of the minigames. The main minigame, infiltration/break-in is also entertaining enough to keep you captivated, while you try to figure out where various nefarious characters are hiding out. The game is dated, for sure, but the premise is well executed and quite rare to see, only Shadows of doubt really comes close to matching the feel of conducting your own investigation. Had the controls been better and a bit more responsive, i'd have given it 5 stars.
