the video posted above and quoted in my reply gives a good view on what you can do on the server itself however the best advice I can give you is to give our server rules a good read before you even log onto the server. (Click here for the rules)
the other advice I can give you is to get a fun group to roll with.
@Daanv Thanks dude i am half way through the video now (up to running pedestrians over lol). I dont know anyone who has this game unfortunately so trying to find people to play with (on here hopefully).
Sorry for the late reply but I am currently not that active due to multiple reasons. I won't be back active for another week or less. If you're still in need of guidance when I return, I may be able to help.
