The Head to Head playlist has returned to Halo 5 to round out the Spring 2019 Season and with that are some changes. The changes, posted by Unyshek on Waypoint, are below.

Maps

Minor geometry adjustments to improve the flow and balance of the maps or to remove exploits

Repaired several inconsistent or broken clambers

Improved respawn locations to decrease spawn killing

Adjustments to weapon respawn times, ammo count, and weapon spawn locations

Game Modes

Reduced the respawn time from 5 seconds to 3 seconds to reduce the opponents time to set up after engagements, decrease spawn predictability, and to add meaning to damage dealt on the opponent after losing an engagement

Sense Power-Up
