Now before you read any further into this, it's a bit of a spoiler, just warning you.
With
The Joker as your mentor you can imagine that the Joker wants you to help him defeat ole Batsy himself. And if that's your conclusion then you're quite right. It can be a lot harder than just beating him up though (unlike other
boss characters in the game) he just won't leave you alone. Sure Joker's there to help but he gets distracted by a few of Batman's heroic antics as he shorts out gas bomb fuses and traps The Joker in a force field sphere. So you keep dying, eventually all your weapons/armor breaks and you have to go to a
Safehouse, fix it all and then go back to the hotel and start all over again. It's just an annoying cycle if you don't know what to do.
To beat the Bat you have to do a few things instead of just pounding into him. After a few good blows to the head (or where ever) Batsy drops a
device which you hear The Joker shout "
Grab the DEVICE! Quick!" Once you manage to pick that up, Joker comes back into action and helps beat up Batman again. A few more knocks here and there and then Bat Brain capture the Joker. Beat up Batman some more and he will eventually drop another device to pick up which frees The Joker. Bash the Bat some more and Joker runs off allowing Harley to pick up some pieces and you to beat the living snot out of Batman. This is the last time his health replenishes to knock him dead!
So here's a few helpful hints, tips and no stupid link tips that send you to other pages who just show you more links.
Tip #1
Don't go straight into the ballroom where Batman and The Joker are waiting. If not already used, take some of the canisters up in the previous room down to where the
showdown is happening. Don't go all the way in, just drop em in there. That'll give you a head start with some health, frost and laughing gas. Use them wisely though, if you die they don't come back.
Tip #2
Use a lot of ranged attacks against The Batman, depending on your level when you go to defeat him you can lose a lot of health very fast.
Tip #3
Try not to use your super powers unless absolutely necessary. It doesn't regenerate and neither does your health (excluding certain parts of the battle)
Tip #4
When the Batman drops the first device, grab it straight away as fast as you can, if you notice he pauses a bit. If you're not quick enough and you miss the opportunity then go over to Joker near the hostages, wait for Batman to be distracted by Joker and then collect the device. (
Caution: If the device isn't picked up before it expires you instantly die, so be quick about it).
Tip #5
When Batman has Joker trapped in the sphere, run like crazy! This is one of the two opportunities you get to regenerate your health in this part of the mission. Batman will stay with Joker and taunt him for a bit (whilst Joker does the same) leaving you a huge gap to get as far from him as possible (down the sides is recommended), wait for your
Health and
Super Power bars to regenerate. Batman's health will have regenerated as well, but if you're a too lower level you'd be thankful for the regeneration, otherwise you'll have no chance.
Tip #6
You have the ability to block and dodge attacks. Use it and use it good.
Tip #7
Let The Joker do a lot but not all the work, he can only do so much and can in fact die. When Harley comes into it, same concept.
Tip #8
Do not quit. As frustrating as it is, just beat him. It is a lot more frustrating coming back to the hotel and beating the crap out of all the Cops and Detectives and then have to deal with Batman all over again.
Tip #9
If it is too hard and you have to quit cause you're on the verge of a mental break down, or smashing your PS3/Computer then quit. But don't smash your console. Play the game, level up and come back to beating up Batsy when it'll be so much easier.
Have fun Bashing the Bat. Open to questions and comments, feel free.
