Crossbow Reach is an early MK the player can unlock that gives a slight increase in a certain stat, like Fraggy Frags or Fast Glue. With the Crossbow, Sharp Shooter, and Crossbow Master already having great range, the difference isn't very noticable. However, it's mandatory to get Crossbow Reach to reach to even better MK such as Master Double Cross or Bonus Monkey!.
Tips[]
With Crossbow Reach, times where the player has to place the Crossbow or it's following upgrades in a precise spot can sometimes be helpful due to Crossbow Reach increasing range.
