6D. DLC Challenges =

Complete all DLC Challenges in Batman: Arkham Asylum, including Totally Insane, Nocturnal Hunter, Heart of Darkness, Hothouse Prey, Crime Alley, and Scarecrow Nightmare.

These are the downloadable challenges available online. For the moment, all of them are free, although some require codes that you could only get if you bought your game a certain way (which will be pointed out for each one).

Although you can earn medals through some of these challenges, none can be applied to your trophies. You must use the in-game challenges for those.

Totally Insane - (Insane Night Map Pack)

This is an infinite style combat challenge that takes place in the Records Room in the Mansion. You'll start with three guys, and more will be continually added as you keep fighting. In addition to the usual henchmen, you'll also be fighting Lunatic Inmates, so be extra careful to watch for their strangleholds, as that will end your combo pretty quickly.

Nocturnal Hunter - (Insane Night Map Pack)

Location: Some Industrial Place

Opposition: Eight

What Goes Up

As a henchman climbs up a ladder, knock him off and back down. You can do this by standing at the top and punching, but this is so noisy, and other ways work. For instance, fling a Batarang at the guy as he climbs. Find a nice gargoyle perch to do this from. It only works if he gets KO'd from the fall.

Last Man Standing

One of the henchmen is in red. Take him down last. He's the one right in front of you as you start.

Smash and Grab

Perform an Inverted Takedown through a glass ceiling. Sneak right into the inside of the building and Silent Takedown the henchman at the far door. Right above you is a weak floor, and right above that is the glass ceiling. Pull down the weak floor, then head out for the nearest gargoyle. Grapple over to the gargoyle above the glass ceiling and wait for someone to spot the body. Grab that guy, but make sure he's not the red one.

Heart of Darkness - (Prey in the Darkness Map Pack)

A Combat Challenge that takes place in a square area that is partially electrified. Stay away from the sides unless you want to be full of juice.

• Round 1: 5 Henchmen
• Round 2: 8 Henchmen, 2 w/Pipes, 1 w/Knives
• Round 3: 12 Henchmen, 1 w/Stun Baton, 2 w/Pipes
• Round 4: 12 Henchmen and 1 Titan, 1 w/Knives

Medal Scores:

• One Medal: 10000
• Two Medals: 30000
• Three Medals: 50000

Notes: If you play your moves right, you can get a TON of points in the last round with the Titan.

Hothouse Prey -

Location: Some Kinda Greenhouse Area

Opposition: Six

Bullet Proof

Suffer no damage throughout the entire challenge.

Pre-emptive Strike

Take out the guy in red first. Go through the vent to the right so you can bypass the first guy, then wait for the guy patrolling this level to pass so you can sneak behind him and drop down to the lowest floor. Once you're there, either use a Sonic Batarang to lure the guy out and detonate it, or use a Multi-Batarang on both of them and take the red guy down first before anyone shows up. Sonic's probably easier, if you don't mind wasting it.

Three Strikes

Perform a Strike on three separate enemies. Isolate one, then punch and ESCAPE. Don't continue punching until they're down or you'll get pegged. Use normal Batarangs to drop the other guys, then drop behind and punch the third. If they're all sufficiently occupied, none should spot you as you return to the gargoyles.

Crime Alley -

This DLC is only available to those who purchased a Collector's Edition of Arkham Asylum. This Combat Challenge puts you in Crime Alley, a somewhat thin and long arena.

• Round 1: 4 Henchmen
• Round 2: 6 Henchmen, Wall Mountings
• Round 3: 8 Henchmen
• Round 4: 12 Henchmen

Medal Scores:

• One Medal: 5000
• Two Medals: 10000
• Three Medals: 20000

Scarecrow Nightmare -

This DLC is available to those who pre-ordered the game through Gamestop. This is a sudden death fight against an endless parade of skeletons, of the type you fight in the Scarecrow hallucinations. Skeletons are far more fragile than regular enemies, but move just the same. The challenge will end once you take a single hit. You'll face types of skeletons you didn't face in the main game, but which are based on enemies from the main game. For instance, there are "Knife Skeletons" (although they're glowing sticks) and "Stun Baton Skeletons" (carrying a torch instead). These guys are fought the same way as their living counterparts. Scoring is the same as it would normally be for a combat challenge, except there is no inter-round scoring. It's all just based on your moves and combo.
