T2: The Arcade Game was based off of the Terminator 2 movie. In the arcades, it was played with video game guns. The home ports for the Super Nintendo and the Genesis are compatible with the Super Scope and the Sega Menacer game guns. However, you may also use the controllers, but the result of that is moving a cursor around shooting things. It isn't a bad way to play, though.
The game tries to follow the movie's storyline by telling it in between certain levels. After waiting for the first part of the story to end, you will end up shooting everything in sight! There are robots coming from both sides of the screen, and enemy planes flying in the sky. Kill them all!! That sums up the whole game pretty much, but the awesome action would obviously keep you playing.
One downside I must point out is that the level where you have to protect John Konner is too difficult. There are several robots and planes attacking the pickup truck. However, there is a way I know to beat this level: Only bomb the planes. Don't concentrate on the robots. And bomb them RIGHT AWAY! Having another player help out would be nice, I guess.
Thankfully, there's a 2-Player mode that adds to the game's replay value. As both of you Terminators get your controllers prepared, you'll be ready for the greatness of shooting mindlessly.
