One you start, addiction.
Firstly, once you get to the title screen, you will probably stay there for ages listening to the music. Then once you start the game, you are on the slightly easy Level 1 called "That Old Army Game". By the time you get to Level 2 called "Red Alert!!" you will be addicted until you get a game over. The graphics are good. The only problem is that level 15 is INSANE. It is merely possible. You have to jump over cans and explosives without the rockets in the air hitting you, but the hardest part is when Scud comes along and when you jump over the cans you will probably hit him and lose a hit point... but actually brilliant game.
You will this game so matter if you using Gens or the actual system, you will enjoy this game.
