Unlike other servers, our DarkRP servers are SSRP ( Semi Serious Role Play ) so character backstories are not needed. Of course you can play along with it but unfortunately you won't find much RP around on our servers.
Also, make sure you have CSS downloaded, or at least the textures which you can find here:
cscheater. If you don't have these textures, a lot of stuff will be purple/black checkered textured for you. Also, expect a lot of large ERROR simbles if you don't have CSS ( CounterStrike: Source ).
Here is a great SSRP guide made by Vitx, an SSRP Admin:
