Every time I hit the share button I just get an upload option that has empty video folders, a screenshot button,and a thing to start broadcasting to twitch but for the life of me I cant find how to make a video. All help appreciated.
One of the challenges is drink 5 things of rum, is it unlocked eventually in the story or something because I haven't found where you can.
When you unlock a bar you have two options go up to the bar tender and pay him 200R to mark a location of a convoy or other secret on your map or usually to the right or left at the end of the counter will be a bottle of rum its easy to spot as its glowing. You should be able to click on the bottle and drink rum for I think 10R a drink.
There is also an achievement/trophy for drinking until you black out so when you do this for the Abstergo challenge keep drinking until you black out and you'll also get an achievement.
