So, there whas this SNES game with aliens (I think), it was something kinda Contra, but I don't think it was Contra.
It was a sidescroller where you shoot enemies/aliens.
What I can recall best is that there was this level, where you entered a place like some tunnels, and there were fans that could suck you, and kill you - lol. At the end of this level, you destroy something/place a bomb and you need to go back all the way and escape the place before it explodes.
Other than that, I remember the soundtrack was very nice, there was a level with snow, and, if I'm not mistaken, I finished the game, and there was some drawing of Eath, or another planet that you freed (or destroyed, lol)
Hope you guys can help me, I remember I really loved this game, and I simply can't remember the game's name.
