Iron Man Guide

Needle Boy

Overall Impressions
Lots of easy stages here. Having The Kid makes a lot of them even easier. That pretty much sums the world up.

(Use The Kid unless I say otherwise)
All level ratings are relative to this world's levels only.

Difficulty: Easy
Fairly straightforward stage with a large area and plenty of room for error.

Difficulty: Easy-Medium
Drop straight down and cling to the walls occasionally so you don't drop too fast. Use double jump at the end to reach Bandage Girl.

Difficulty: Medium
Drop to the lower level only after the gear at your current level has fired. 

2-4 (Use Jill)
Difficulty: Medium
Ah, the fans. These things blow up straight up when you're on top of them. The closer you are to the fan, the higher you'll be blown up. Use Jill for this one because her air brake allows you to reach the bottom of the fans (and thus get blown up higher)easier.

Difficulty: Easy-Medium
Jump on the fan above, and when you're in the air, jump to the left wall and just get to the very top and head right. Alternatively, you can head right, take the fan there, and climb the right wall.

Difficulty: Medium
Jump to the top of the structure, then drop down the hole that's above the 2nd fan. Head left, drop down, and do some platforming to the right. Ride the fans up, and you're done.

Difficulty: Easy
Just keep wall jumping until you reach the top.

Difficulty: Easy-Medium
This level is pretty straightforward. Just watch out for any slugs and spiky surfaces, utilize double jump well, and you'll be fine. 

Difficulty: Easy
Just do a running wall jump to clear the two gears in the middle of the area. Rest of the level is simple. 

Difficulty: Easy
With double jumping, you can just slide down the cage and double jump to the other side to get the key when you start falling. Repeat this to reach the other side.

Difficulty: Easy
Hold the run button the whole way and this level isn't too hard.

Difficulty: Hard
Probably this world's hardest stage, but that isn't saying much. If you start doing running double jumps to the left as soon as you grab the key, you can make it to Bandage Girl before the gear shooters have been unlocked. Otherwise, just wait until the gears that are fired hit the ground before jumping to the next platform. 

Difficulty: Easy
The purple blobs (ulcers) shouldn't be too much of a hindrance. Double jumping and running will get you through the level in no time.

Difficulty: Easy-Medium
If you get on a fan's wind area while you're falling, you'll float nicely. Use this and double jumping to your advantage to get through the level easily.

Difficulty: Easy-Medium
Just take your time and you should get through the stage easily.

Difficulty: Easy
If you want, you can start climbing the left wall at the start to avoid the first two lasers completely. For the last one, just advance carefully and cling to a wall when it's about to fire.

2-17 (Use Meat Boy)
Difficulty: Easy-Medium
With Meat Boy, you can reach the first gap immediately from your starting point. As is usual with lasers, just go about the stage carefully and you'll clear it easily.

2-18 (Use Meat Boy)
Difficulty: Easy
Simply get the key and run to the starting point. 

Difficulty: Easy
Just take your time and anticipate the laser fire. When dropping down, cling to the walls and you'll be safe from the middle laser.

Difficulty: Easy
Double jump to the left wall and just keep climbing that until you get to the top, then head right.
