GROUPS IN QUICK PLAY

The Max Group restrictions in Quick Play stopped being enforced in the June 21st patch, this issue has been fixed with the July 19th patch. As of the July 19th patch, The Max Group Restrictions Variable will be exposed for future tuning. The default setting will be set back to Max 5 people in groups as of the July 19th patch. Max Group Restrictions 5 means each team can have can have:

  • one 4-player group, or
  • one 2-player and one 3-player group, or
  • two 2-player groups

BUG FIXES

  • Hill Climb nodes now function as intended and will reduce the slow down rate of your mech when going over sudden changes of ground slope (rocks, uneven terrain, small hills, steps, etc.). This node was acting in reverse previously.
  • Clan Ultra Auto Cannon 10 now deals full 10 damage instead of 9.9999, which allows it to destroy a UAV within optimum range in one shot.
