Dauntless, the co-op monster-hunting RPG from former League of Legends devs, has finally locked down a release date. Granted, Dauntless has been playable in open beta form for months, but the full-release version of the game drops later this month. Developer Phoenix Labs promises a variety of new features for launch, including a “massive” campaign revamp, and a new Mastery system. You can get the full lowdown on the improvements, below.

　　Dauntless will launch with numerous new improvements and content updates that recently arrived in the PC Open Beta. The Mastery system offers a new way for Slayers to hone their skills, earn experience, unlock achievements, and acquire new rewards. Each Behemoth and weapon has its own unique Mastery card for players to delve into.

　　Slayers can also look forward to a massive campaign rework. Everything from questing and crafting to meeting other Slayers and pursuing Behemoths has received massive updates. The rework also introduces a brand new “End of Hunt” screen, providing Slayers with a wealth of information, including progress made in various Mastery cards, quest rewards, Behemoth break parts earned, and more.

　　Dauntless will launch alongside the new Season 5 Hunt Pass, which will give the game a spring makeover with the Moon Blossom Festival. Of course, the Hunt Pass will include plenty of new cosmetics which can be earned by working through the game’s 50 tiers. Dauntless' Hunt Passes offer both a free Basic track and an Elite track, which costs 1,000 Platinum (around $10) to unlock.

　　Dauntless is free-to-play, although Phoenix Labs will be offering an Arcslayer Pack for sale at launch. It will include a mech-inspired armor set, Platinum, and some consumables. A price hasn’t yet been stated for the Arcslayer Pack.

　　Dauntless hits PC, Xbox One, and PS4 on May 21. The PC version if Epic Games Store exclusive.
