Last Month the Japanese try to retrive this mod a little bit more. They played in the at 2pm CET. At the moment the gametracker,com Server Monitorring is off. Hope soon they turn it on. The ranking seems to work.
I think I still have version 3, I'm not sure what the differences were though. I don't think I ever labeled it as version 3. The version I have installed has a hidden nuke that blows up everything and everyone in the map, but it was causing the server to crash so it was never put online. I'm not sure if V2 has the half pipe in the lower-left corner, if not, then yes, I have V3 and can put it up online. You can only play it on your own computer though, because like I said, servers crash when everyone and everything blows up simultaneously!
I seem to recall that in V2 people had problems with completing the buggy race because of the underwater section. I can verify that I have fixed that bug in the version that I have, so I guess that's v3??? I'd need someone else to verify that for me.
