Platform: PC
Genre: Platformer, naval, action...
Year it was released: No more than a decade and maybe even a few more years, it could be a few years less than a decade, too... not so sure.
Perspective: Side view, 2D.
Protagonist: There was actually a selection between a gun boat, naval defense station thingy with guns on it, and if I'm correct there was one or two more vehicles.
Enemies: Bomber jets, fighter jets, not completely sure if there were naval enemies.
Setting: Modern, more or less.
Memorable Moments: I remember the first level was only an ocean at night (Not sure, most of the chances it was night.). The next level had an arctic background, icebergs, etc... it also had new enemies. Sadly, the second level stopped 5 seconds after it began to ask for a serial code since the game version was trial/demo. Also, I remember that the HUD had Roman numbers (I, II, III, IV, etc...) and I don't remember why they were there, perhaps weapon level or upgrades. I'm also almost sure that the enemy planes were green colored, most of them if not all of them.
I really liked the graphics of the game at that time, even though they are kinda old now, I considered them very good unlike other games at that time.
Note: It's NOT a flash game, it is downloadable.
That's pretty much it, I would be very thankful if someone could shoot out the title of the game.
Thanks in advance.
