Sparky's updated Pwnage with Hourences recently released ONS-Dinora:
The map takes place along an Irish influenced beach which got recently smashed by a rather large storm. To put it simply, it's rather unique and I'm in love with the sand/water textures. Powercores are located in churches up on cliffs, I reckon they could have looked a little more solid to be honest however. He's also covered up the PowerNodes with wooden planks, and I must say they work really well.
This is also the first Onslaught map to make it on to Pwnage, so I guess you could say it's worth checking out. Hit it.
