Those tanks will be prowling the European servers between 5:30am GMT on December 4 and 5:00am GMT on December 8 and you should keep your eyes peeled across all tiers. Gunning down one of these vehicles will gain you 500 gold, although Wargaming would like to remind all players that there is one caveat…
…no teamkilling. Gunning down an ally because they have a bounty on their head won’t earn you diddly squat, so don’t even think about it.
All you need to do is join a random battle and look out for the big, gold tanks. They won’t be subtle. Should you claim a kill, the servers will log it and you’ll find all that shiny, shiny gold waiting for you back at the garage.
