Cobra Triangle is a.... different game. You are a boat in the "Cobra" (Bermuda) Triangle. You have a variety of tasks to complete. Thier are 7 different types of levels. They are Race to the Finish (a race), Collect the Pods (a bonus level), Dispose of Mines (guess what you do), Fry the Monster (you fight some Loch Ness Monster), Guard the People (self explanitary), Reach the Finish (you drive upstream dodging objects), Shoot Targets, (another bonus level), and Jump the Waterfalll. (yes, you jump waterfalls.)
The game is really fun until you reach the Jump the Waterfall level, which is impossible. It is kinda like the bike level on Battletoads, except the jumps move left to right. This whole level ruins the game, unfortunatley. I've beaten the level twice. The worst part is that you have to do it more than once. The first time is in Level 7 and then you have to do it once again in the later levels. The graphics are decent and the music is solid too. The gameplay is completely original, and that is why I think it is so cool. You can also collect power-ups to make your boat faster and make its weapons stronger. The powerup method is very similar to Gradius and Life Force. The game is pretty good, I would reccomend buying it.
