The Title Update will allow players to adjust the level of reticule bloom on Semi-Automatic weapons. The variable is between .00 and 1.00.
Also, the sword can no longer be blocked by non-melee weapons. Sword clashing will only occur when 2 players with swords lunge at each other, instead of Reach's current settings, which allows guns to initiate the "clash" animation, blocking the sword lunge from killing you completely.
