Hey guys so i last played in the end of 2016.I left i dunno maybe the game got boring for me.So i downloaded today and i merged and started playing my old account i have 26hrs in it ( i know not too much but still more than 0hrs).I joined in and i had no idea wtf is going on.I forgot the controls,the basics,the aim,the story,what i was going to do,my strategy.So basically my question is do i forget about this account and start a new one or do i try to figure out this one?I really need help..s
