PlayerUnknown's Battlegrounds' latest limited-time event mode is Desert Knights—the 50-person deathmatch that debuted in May, but was prematurely pulled as a result of server issues. 

Set on Miramar, ten squads of five drop into the desert, tooled up with level three gear and a crate weapon. The first team to 200 points, or the team with most points after 15 minutes, wins. If you die, you respawn above. 

"As the sun slowly climbs over the horizon, five soldiers stand ready," says this Steam Community update. "Armed to the teeth and kitted out for battle, these warriors know things are about to heat up the cool desert morning. Their orders as tall as the shadows cast by the rising sun, the Desert Knights are ready and aim to be the last squad standing." 

Desert Knights take two kicks off at 7pm PST this evening / 3am BST tomorrow morning. It runs till the same time on August 26/27, and is available in TPP and FPP in North America, Europe and Asia; but is restricted to third-person servers everywhere else. Let us know if you plan to drop in. 

It's been a busy week for PUBG, having also announced its long-awaited Training Mode at Gamescom. That's as yet without a concrete launch date, but will feature a shooting range, racetracks, and parachute practice. 

The new thing teased yesterday by Playerunknown's Battlegrounds creator Brendan Greene has been unveiled as Training Mode, which as the name suggests will give players an opportunity to learn and master the game's mechanics without the risk of being murdered if they stick their head up.   

Training Mode will support 5-20 players on a new 2x2 km map with facilities that cover all aspects of the game: There's a shooting range, as Joe speculated, plus practice areas for parachuting, melee, parkour, and "throwables," multiple racetracks, an indoor CQC range, and more. The idea is to offer something for everyone: Newcomers can get a handle on the basics without being shot at, while dedicated players can familiarize themselves with more advanced features like weapon attachments, recoil, and bullet drop.   

"We wanted to go beyond what players were asking for, so we didn’t want the map to be just a shooting range, but an open, living map where players can test a variety of skills to their heart’s content," senior designer Dave Osei explained. "The map is broken up into different sections; short and long range combat, vehicle races, jump skills, vaulting, vehicle ramps, etc. Each one of these sections represent a gameplay situation players may become involved in during normal gameplay. You can freely move around the map to practice whichever skill you like." 

The new training ground is also designed to be expanded in the future, Osei said, "with room to introduce new areas as well as ideas players want to see implemented in the future." 

Training Mode is still in development and some of the specifics may change before it goes live, which is currently targeted for September. As it stands, this is what you can look forward to: 

• Incremental range targets: 800m Range, 400m Range, Special 1k Range target
