Hi there Pertti49. Like what I'm seeing! :thumbsup:
If you haven't already used this wood spike to stop tanks look at this:
http://ofp.gamezone.cz/ (scroll down a bit, till you see the article about the wood spike.
)
Just a suggestion. You probably made your own or used it already, and Im just can be bothered looking at all the pics again..
Nice work though, and looking forward to seeing the article for myself...
Good job,
Waterman.
