  • The Vindicator’s grenade explosion effect should no longer crash users running a GTX260 graphics card.
  • Fixed a bug where marines would continue to be buffed by the Damage Amp if they were standing in it when it expired.
  • Fixed ammo usage on the Tesla Cannon to properly decrease 4 times a second instead of 2 (doubled clip size to account for this).
  • Rebalanced Tesla Cannon’s damage to encourage it to be used more as a support weapon.
  • Tesla Cannon will now use ammo slowly even when it isn’t damaging something.Fixed Unicode text chat
