The only alternate suit I have seen is the Armored version, unlockable after beating the games story mode. Sadly, it is only for Challenge mode.
About 6 - 8 hours of gameplay.It has replay value though because there are tons of stuff to unlock through out the game.
you dont unlock him but you do help him in the middle of the game
You unlock the Riddlers' hideout.
You need to find various Riddler trophies and interview tapes hidden throughout the entire game. Plus, if you find all of the trophies, interview tapes, and all of the Riddler's challenges you unlock an achievement (I'm guessing there is a trophy on PS3 that's the same). Games Radar has an amazing Riddler challenge walkthrough. http://www.gamesradar.com/f/batman-arkham-asylum-riddler-guide/a-2009082614217603032 I suggest beating the game first, however, before doing the Riddler's challenges.

In Batman Arkham Asylum on ps3 you can actually be the joker! You must unlock the mission in which you can be joker and play it in the Challenge Mode. You have to progress through the game to unlock the mission and finish some riddler missions. If you are logged in you may be able to succesfully do challenge Missions, Sometimes you have to download to the latest ps3 version, and you may also do other Challenge Missions in the Challenge Mode.
To access the fireworks in Batman: Arkham Asylum, you need to locate and solve the Riddler's challenges scattered throughout the game. Once you complete certain challenges, the fireworks will be triggered as part of the game's celebration sequence. Keep an eye out for Riddler trophies, riddles, and puzzles to unlock this Easter egg.
