The spawn rates of both difficulty's the final waves were dropped by one tier (1 -> 0.7).
The platform will no longer disappear early between wave 2 and 3.
The platform arrangement in the final confrontation now gives a lot more room to maneuver.
Once the Magna Exie in the final wave has been defeated, there's one more additional route back there from the middle.
The final wave weapon on normal mode has been changed from Dragon Soul to Decoy Beam. It was a fun idea to use Magna Crush to jump through the Dragon Soul, but it's a bit sudden to request the player to do as a new thing on the final challenge with a lot going on.

Hard mode has one additional time for Shadow Metal (now you can hear trumpets AND shadow metal clanks)!
Added an additional dog in hard mode.
