Summary
Less than playable.
The Good
The MAD property should have been better used, but it wasn't.
The Bad
Barely a game, Spy vs. Spy has no distinct objective. The graphics were sub-par for NES. The sound effects were ear-splittingly awful -- without the charm of the original Atari blips and beeps.
The Bottom Line
What was the point of this game? Really, I never knew. Spy vs. Spy features extremely poor gameplay. There is no real goal, just a lot of object interaction. The entire experience becomes tiresome very quickly.
