This game was one of my favorite games to team up and challenge an awesome military force. Better than that one that was an over the top view and you could get into a tank, forgot the name of that one, but this one I could never forget. I also liked the original Mario Brothers too, as that one was rather fun to play with a friend as well. This one has you as one of two military tough guys, one nicknamed Mad Dog and one Scorpion as you traverse jungle terrain, futuristic bases and the innards of a very large and very unfriendly looking alien battling the forces of the Red Falcon, whose name really did not make much sense as the alien looked nothing like a falcon, but I guess that is just nitpicking on my part. You run through each level blasting all that gets in your way using your standard gun with unlimited ammo! You also get upgrades that increase the rate of fire, gives you lasers and flame throwers and of course who can forget the spread gun? When you and your friend had this deadly weapon, alien forces watch out! Annihilation ensues! The stages vary a bit to give you a different experience each time as you have your horizontal moving levels, vertical levels and the strange 3-D type forward moving stages. You battle a boss at the end of each stage as you make your way through the many enemy forts on your way to blasting away the 'heart' of the operation. Fun game, hard as heck thanks to the fact it was a one hit and your character is done type game, I was ever grateful for the code that made it so you had 30 lives!
