just finished the game, there are 2 endings, help the government (easy, short and evil) or help the desert patrols (hard, long and heroic).
@Teabags_91: fuel is sold in Hara (mostly)
it could be better with a sequel, or with new missions, new maps and stuff, it get a little repetitive after playing for a while...
but is a great game and its kind of addictive!
