first off, you need to be in the right forums. *it sounds like you're asking for help with a PC game, and this is a Playstation forum.
second, you need to know the name of the game you're having trouble with, and be sure you mention that name somewhere in your post. *the best place for that would be the title. *is Power Plant the name of this game?
third, try making sense and more than the left over near the third or maybe forth but i forget once you're there and the guy with the laser powered carrot booster stops singing. *you know what i mean?
