Halo 5: Guardians developer 343 Industries is taking action against players who work the system to boost their Req point and XP values or use exploits to gain bonuses they haven't earned. Writing on Halo Waypoint, 343 said it has identified offending players and is enacting bans and other punishments to clean up the virtual battlefield.

"We've been keeping a very close eye on Req point and XP boosting, and the exploits some players are using to idle in matches in an attempt to fill their very own Money Bin with a ton of REQ points and XP," 343 said. "Our data team at the studio has not only caught this behavior, but we've also started taking action against offending accounts, including bans and removal of all REQ points."

343 added: "Most of you need not worry about this, as you're aware that Req points and XP are only awarded for honor and bravery on the battlefield."

The same blog post covers a variety of other Halo 5 subjects. It also mentions that the fan-favorite SWAT mode is changing somewhat. Effective immediately, the respawn timer has been lengthened from 1 second to 3 seconds. According to 343, this should "improve overall game flow while still maintaining the fast-paced action the playlist is known for."

In addition, friendly fire has been removed from SWAT. No longer will you kill a teammate who jumps into your sights at the wrong time. It also means teammates won't be able to troll you as severely.

Also in the blog post, 343 shared some close-up images of some of the new Reqs coming to Halo 5 this week as part of the game's free Battle of Shadow and Light expansion.

The Battle of Shadow and Light expansion is set to arrive "within the next few days," 343 said. It also adds the Big Team Battle mode and four new maps inspired by those seen in previous Halo games.

Battle of Shadow and Light is now available.
