The Halloween event Junkenstein's Revenge has three difficulty options to choose from - easy, medium, and hard. Aside from playing at a level that feels challenging enough to be enjoyable, is there any reward difference (EXP or other unlockables) that would encourage playing at higher difficulties?
There's no way to play beyond Hard mode.
There are achievements for beating Junkenstein's Revenge for:
- Beating medium (Junkenstein's Revenge spray)
- Beating medium without any damage to the door (The Reapening spray)
- Beating hard (Halloween Special spray)
- Beating it using every hero once. (Rise of the Zomnics spray)
Each achievement of course has its own spray tied to it as a reward for gaining the achievement./
EXP is usually doled out by time played, and since typical Junkenstein matches take 6 - 8 minutes, I get roughly 2 - 2.2k exp. I tested this across easy, medium, and hard, and found no difference in EXP gain (completed all 3 modes).
