117 K after 12 turns! That's crazy !!Welp, unless you have a ridiculous amount of HP you get 12 turns to kill Joker before he uses a 117k attack on you. Not to mention the jammers, poison orbs, and 21k potshots he takes at you beforehand.
The BGM is Batman as fuck though.
On which difficulty is this?
Won't GrOdin work fine cutting that damage to 20% only?
