Sentinel

Sentinel's gameplay equal parts repetitive and boring, and the light gun's accuracy could stand improvement as well. The single strategic element is that when the orb is "powered-up", shooting it destroys all on-screen enemies, like a smart bomb. Big freakin' deal. The mountains, buildings, and volcanoes in the background certainly look better than the plain 2600 version, but there's nothing here that will catch your eye. The monotonous background music will give you a serious headache. You can turn it off using the difficulty switches, but that also turns off the sound effects! Sentinel is a complete dud, and only serious collectors should take note of it.

Sentinel becomes somewhat challenging by the third stage, but by then your trigger finger will be aching terribly. I actually had to switch hands just to sooth my cramping muscles. This game is awful. If not for the physical pain it inflicts upon you, Sentinel would be completely forgettable.
