I bought this game of ebay with no paperwork.....
I am up to the task in the car park where I have to get the rocket launcher to destroy the tank. My question is....How do I change weapons in this game. No key on my keyboard will let me change weapon although the default key (F) lists my weapons on hand, but, thats all I can do. Please help as I cant continue without blowin that friggin tank up, and my rifle wont cut it.........Cheers

You use (F) and scrool button on mouse. When found press it.

Thanks for the help, but unfortunately that was the first thing I tried, mouse wheel does nothing. I wonder wether my 2 week old mouse and keyboard are the stupid thing about all this..........Cheers

OK then try to use (F) and mouse scroll button but when found yust release (F)

You need joust to press and hold ( X ) button.

And you need to stay near, near, NEAR that artillery tank!!!
