The Punisher is in the exact same scenario as seen in Batman: Arkham Asylum. His mission is to make it through the Asylum and kill every villain he meets along the way (basically, all of the villains you meet in the actual video game). He must also go through the same tasks that Batman had to go through in the game (rescuing Commissioner Gordon, saving hostages, finding the Titan Formula, etc.)
-Morals are off for everyone.
-Punisher must kill every villain that he meets in the Asylum.
-None of the villains have any knowledge about Frank (Frank has no knowledge on their capabilities either). The villains are expecting Batman to show up. The exception to this is Joker, who has full knowledge on Frank.
-Punisher has the following equipment: M4 assault rifle (four clips); Glock 19 (two clips); P90 (one clip); two smoke grenades; one frag grenade; one flash grenade; one fully-functional replica of Batman's Cryptographic Sequencer (with knowledge on how to use it). Frank also has his usual Kevlar costume, as well as a comlink that allows him to communicate with Oracle. Finally, he has a special set of goggles that can duplicate Batman's "Detective Mode".
-If Punisher runs out of ammo, he is able to take ammunition from any thugs he kills.
-The Punisher starts out at the beginning of the Asylum. Joker has already gotten loose and is in his hideout.
Can Punisher make it to the end and take out Joker?
