Just started playing an early access game called Blackwake ( http://store.steampowered.com/app/420290/ ).
It's a pirate Vs royal navy old sail ship PvP battle game.
So far i only played 2 Vs 2 galleon.
Each team has two galleons with a full gun deck below deck and a few guns on deck. aswell as several svivel guns. Each galleon is crewd by 13 people.
You need to load the cannons (multiple shot types), repear damage, pump water, put out fires, repel border, grapple and board enemy ships and all other glorius ship battle stuff.
it is early access, but very few bugs and fully playble.
anyone wants to join up, it could be fun practise before we can do real multi crew missions in Star Citizen.
