Players have discovered plenty of interesting issues in the ongoing Halo 5: Guardians multiplayer beta, but this is probably the funniest.
"Not sure if anyone has shared this before, but this is what happens when you crouch in midair and sprint upon landing at the beginning of a breakout game," wrote Redditor coked_up_tourist. Other users piped up in the comments to report that they've seen the same thing happen in their games. One labels it the "Spartan poop stance."
The Halo 5 multiplayer beta ends January 18, so get your crabwalking in while you can.
