Halo 5: Guardians received Grifball in a recent update, but it’s not working as perfectly as some may have hoped. The Halo community has brought a couple issues to developer 343 Industries’ attention, including one that could ban players by accident (via Eurogamer).

The accidental banning of players stems from the Gravity Hammer, which is used in Grifball as a form of defensive play. It causes splash damage, which often results in unwilling betrayal; after getting hit by a friendly a number of times, Halo 5 sends a message, asking if you’d like to “Mark the Betrayer.” If you choose “Okay,” the betrayer is disconnected from play, while “Dismiss” does exactly what it says. The problem is that the message can pop up unexpectedly, and players can select to ban the player by complete accident.

343 says it’s looking into the possibility of altering betrayal thresholds. However, it isn’t the only problem Grifball seems to have. Reddit user PraetorianiRex found an exploit that allowed them to drop the ball into an unreachable area. Another Reddit user, who goes by Swolley, found a different exploit that allowed them to leave the arena entirely. You can check it out here.

The developer has responded to both exploits and let players know they’re working on fixes. Despite the mode’s issues, Grifball seems to have been received well by the community. One Reddit user even discovered that the Gravity Hammer has an assassination animation.

Sports seem to be on the mind of Halo players, as Reddit user DaveS1551 has shown off a new game type they’re working on. You can check out “Spartan Basketball” right here in an animated GIF that showcases a slam dunk.
