- Hot and Cold

Side-Mission - Hot and Cold

This Side-Mission is flagged by a chat with a tied-up Harley Quinn when you are on your way to the Joker Boss Battle -- you encounter her in the Steel Mill, and while the circumstances that lead to her being tied up and gagged and left in an isolated section of the Mill are not explained at all, in addition to flagging this last Side-Mission for us, she gives us an important clue about where it begins. 

You know, Harley is not as stupid as she appears to be and acts, so it is obvious that the little slip about the location as well as the fact that Joker has some of the tech invented by Freeze is very likely her way of getting revenge, the question is, revenge against who?  Joker?

Either way it really does not matter!  After you have dealt with the Joker you can either continue the story or head for this side-mission.  Personally I went ahead and completed the single-player story prior to doing this one, mostly because of the circumstances that prevailed in the city following the Joker Boss Battle -- you know, the attack and mass destruction?

But you are here now, and that means you want to complete this -- so let us do that!

-- Locating The Tech Storage Pile --

To begin this playing as Batman, return to the Steel Mill and enter via the hole in the roof that was made by the initial Protocol 10 Missile Attack -- this leads to the room you were in for the Joker Boss Battle.  The area of the map in which the stock pile is located is not one of the parts of the Mill we have previously visited, so it does not appear on our map as a discovered area.  We need to remedy that.

Look at the southeast corner of the room and you will see a security gate with a motor above it -- use the REC to raise the gate to reveal a set of double doors -- and when you go through them you add another area to the map: Freight Elevators.

Before you hack the console for the lift look to the left to spot a round hatch -- Batclaw the hatch to Grapnel it open and reveal a Trophy that you use the Batclaw to pull to you and claim.

Completing Hot and Cold

-- The Lifts --

After you hack the console for the lifts the gates open and you see that there are two lifts stuck halfway down the shafts and the power seems to be off.  In the one on the left there are three thugs, in the one on the right a Trophy.  The lift on the left has a motor on top of it but the one on the right does not, and the left left has an open hatch to give access while the one on the right is blocked.

First, drop into the left lift and take out the thugs, then stand on the top of the right one and activate the motor on the left to raise it, and drop down its shaft now that you have access to it, stepping out of the way if it should come hurtling back down!  This gets sort of complicated now...

The right lift is actually partially destroyed, and is sitting above the open door for the Basement Level, and outside of it are some thugs inlcuding an armed one, whose conversations you can overhear.  There is a demo-floor at the bottom of the right shaft as well.  So first, RB up to the right lift and grab the Trophy there to get that out of the way!

Now drop to the bottom of the shaft and blow the demo-floor; drop down and you are in the machine area of the shaft, where there is another Trophy for you to take.  Grab it then climb back out.  Now it is time to exit the shaft and deal with the thugs above -- but remember one is armed!

The easiest way to deal with them is to RB up, drop a smoke pellet, and then KO them at your leisure!  When you are done use the REC to destroy the Harley Quinn Statue here, then use the REC to raise the gate on the other side of the door, open the door and go into the Boiler Room!

-- The Boiler Room --

Now if you check the map the area is on it -- and this is where the cache is located along with a group of thugs that includes a trio with SMG's, an armored thug, and a Greenie as well as some regular thugs.  You want to interrogate the Greenie so try not to kill him, right?  The armed thugs are the priority -- the armored thug is in an ideal location for a silent takedown but I am chagrined to admit that I did not know you cannot do that with armed thugs.  I tried and he basically laughed at me, and the barny commenced.  Taking out the armed thugs was easy enough, but the Greenie makes it really hard not to hurt him as he is all over you -- so using the mega stun on him is a good idea.  I am just saying.

Once you have them taken care of you get to see what they were shooting at!  It is a Penguin Shooting Gallery and how about that?  Using your trusty Batarang, destroy all of the Penguins to reveal Trophy that rides along on the belt.  Use the Batclaw to grab that as it passes by!

-- Wrapping Things Up --

In the small area adjacent to the main Boiler Room you will first spot a demo-wall -- blow it and take the Trophy that is behind it, and then to the left is the box with the Freeze Tech in it.  Walk over and pick it up (use 'A' when prompted) to claim the Freeze Cluster Grenade -- which also happens to be the final Bat Gadget in the game!

Taking the box unlocks the Achievement "Fully Loaded" (10 GS) for unlocking all of the Bat Gadgets, so good on ya mate!  This also completes the Side-Mission, so double-well-done!

Now backtrack to the exit of the Steel Mill and return to the section of the Main Guide that you came here from!
