Believe it or not, Game of Thrones: Winter is Coming is four years old.

Game Hollywood Games is choosing to mark this major anniversary with a series of in-game events.

More on those later. First, a brief reminder of what the game is all about.

Based on the outrageously entertaining HBO series, Game of Thrones: Winter is Coming is an epic, visually stunning strategy MMO that sees you filling the shoes of an ambitious Westeros lord as you attempt to bring peace to the Seven Kingdoms.

If you’ve seen the show, you’ll know that this peace is a pretty remote prospect.

In reality, you’ll spend your time forging alliances, carrying out shocking betrayals, building up your stronghold, and fighting battles in a range of recognisable Westeros locations affected by multiple weather types.

Game of Thrones: Winter is Coming is a real treat for fans of the show. Not only does it feature accurate renditions of characters like Jon Snow, Jaime Lannister, Cersei Lannister, Daenerys Targaryen, and others, but it also lets you play out your favorite Game of Thrones moments.

It’s a pretty robust strategy game, too, with massive PvE and PvP battles that see you picking formations, selecting commanders, and deploying abilities for maximum tactical impact.

To celebrate its fourth anniversary, Game of Thrones: Winters is Coming is letting every player with a castle at level 20 or above claim a free gift, as well as giving you a chance to obtain a limited edition avatar frame and castle skin.

All you need to do is log in and visit the anniversary page, while logging in every day will get you a steady stream of free rewards.

The 4th Anniversary Festival is live right now, and that means the War of Kingdoms is underway.

This vast event lets you lead your troops into battle alongside the 10,000 other players knocking around in the Game of Thrones: Winter is Coming universe, all of you secretly hoping to claim the Iron Throne. Probably.

Game of Thrones: the Night King will return with White Walkers on the 10th of April as they attempt to invade Westeros once again. Royal Lords and Ladies from all Fully-Open Kingdoms will join forces with the Night’s Watch to defend Westeros from the White Walkers army. There will also be a  New Ranking Board added for the defeating of Night King. The quicker you defeat the Night King, the better the reward will be and there’s also the chance to get a special exterior for the Kingdom.

On top of all that, Game of Thrones: Winter is Coming has received a new version of the Weirwood Tree Trials. From now on, you’ll receive stage rewards automatically over time rather than having to manually blitz through stages to earn them.

To begin your Westeros adventure, head to Game Hollywood Games and start playing for free right now.
