Fog Of War
If you're one of the players that started OF-EX4 for the first time and saw this:
DO NOT FEAR. You are not alone, and this is a bug, not a feature of the map. EX stages are supposed to be challenging, but not THIS challenging. A fix for this issue has just been pushed through, and the map should now be visible. As for the reward for our pain and suffering? 200 Orundum! What will you use it for? Maybe like me, you'll use it to fail again to pull Schwarz, and endure more pain and suffering!
