Season 1 of Fortnite Chapter 2 rolls on, and while Season 2 won't be here for a little while longer (20 February at the earliest), Epic Games are still adding plenty of challenges to the popular Battle Royale. They need to; this season of Fortnite has been the longest in the game's history (they usually run for 10 weeks - this one has topped 16 already), and player interest is starting to wane. Luckily, this week sees a bunch of new events and content to play around with, including the next Fortnite crossover with a big movie event. Here's everything you need to know: What is Love and War? Love and War is this year's Valentine's Day event in Fortnite, "the perfect time to party up with that special squadmate" say Epic. The event brings a new Limited Time Mode (LTM) to the game, in which you team up to "become the best" or "take down your friends and flex your skills." Teams of six players take part in a game that lasts a maximum of seven rounds - the first team to win four rounds achieves victory.Achieve total victory by winning 4 rounds. To win a round, your team either has to destroy the bomb side (Attackers), defend the bombsite (Defenders), or simply eliminate the enemy team. (Image: Epic Games) During each round, you can earn gold by eliminating enemies, planting or defusing objectives and completing rounds, which is then used to purchase weapons, shields, and additional building materials. Gold carries over from round to round but resets after switching sides. As you play, you'll complete Love and War challenges and to unlock free cosmetic rewards like a Pickaxe, an Emote and more. There will also be all new Outfits and Pickaxes in the in-game Item Shop. When is Harley Quinn coming to the game? Fortnite's had a number of tie-in events with major movie releases in recent weeks, from Star Wars to Batman, and another is on the way. So what can we expect? The Item Shop will feature the Harley Quinn Bundle, which includes the Harley Quinn Outfit and Harley Hitter and Punchline Pickaxes. If you’re up for hi-jinx, Harley arrives with new Challenges that will transform her from Lil Monster XoXo Harley to Always Fantabulous Harley. Quinn is expected to arrive in the game on 6 February at 7pm ET (7 February at midnight UK time). What else is new? The biggest addition that v11.5 of the game brings to Fortnite might not seem obvious at first, but some changes to the game's code mean the game could be going in an exciting new direction in the future. Fortnite will be moving to Unreal Engine’s Chaos physics system, a new method of rendering physics and destruction in-game. "The goal is to ensure that Fortnite still feels like Fortnite," said Epic, acknowledging that "we’ll be closely monitoring your feedback from the in-game Feedback tool for any issues you may be experiencing. " "To report issues via the in-game Feedback tool, select Feedback in the main menu and choose Bug. We encourage you to put 'Physics' in the subject line and include a concise message in the body that accurately describes the issue(s) you’re experiencing." What that essentially means is that Fortnite will be getting more realistic destruction in physics in the near future, but it should play as near enough the same game. There are also a number of bug fixes and tweaks included in the update. For a full list of patch notes, head to Epic Games' blog post
