September 15 is the annual Battle of Britain Day, and to commemorate the occasion, War Thunder is holding a weekend-long event until September 18 called a "Royal Joust".
All pilots are your enemies, and the winner is simply the first to defeat eight others. The winner will earn 120,000 Silver Lions while pilots will earn 15,000 just for entering.
They've also released a special video for the event from their Legends series, which you can check out below.
