The new hotseat update allows you to play against yourself. With this new update you can easily farm for boxes for as long as you want. Just go to skirmish and set it to deathmatch 600 hp. Aim out of the map and put something on your spacebar and go afk to pass time. When your ready to collect the items then grab all the boxes, doesnt matter which tank collects the boxes even if Player 2 collects the items you get the items. This is what I got in just 2 hours! https://gyazo.com/b00297ead50646616f41bc400b0d232e Also you can get Tank Coins too but you have to manage the spacebar and when you see a Tank Coin box then lift your finger off the spacebar and aim for the box and grab coins. I came up with this idea first as soon as this hotseat update came out so give some credit to me.
