Awesome shooter. I love Twin Cobra. I played that game so much back in the day. I would always get to the 2nd round on one credit, you know after you beat the last boss and it would start over but be harder and the screen scrolls alittle more to the right. Great game, it was nice to get so much play time on a shooter. If you think about it the older shooters always allowed for longer games. Terra Force for example, that game was easily beatable on one credit.
