I'm pretty sure I've never played Rainmaker on Saltspray Rig before. I think there were problems with the map. Anyway, my inexperience probably shows, as I didn't take a minute to recon the map and its changes before plunging in, with my Splatterscope no less.
I think I did okay in the end. Not great, but not bad. I like the changes to the map too, breaking up the sight-lines to prevent chargers being too powerful, and adding new inkable paths to make the mode viable. It's all still a bit claustrophobic, which makes the battles pretty tense. I like it!
