Act 3 - Chapter 1 - The Constructor - BOSS | Act 3 - Chapter 1 Bionic Commando Guide

Hidden bonuses: 2
Level walkthrough: Ignore a small landing pad located in front of you, because you'll return here later on. Instead turn around and get to the top of a red platform. Doing this will allow you to collect the first bonus item.
Head down and approach the ledge. You should notice the second bonus item floating in the air. Make a suicidial jump and catch the object. Once you've taken it quickly attach yourself to a wall and return to the upper levels.
There are three cooling mechanisms in the area and it'll be up to you to decide in what order you want them to be destroyed. I would recommend that you start off by heading towards the device where several pods have landed. Make sure to eliminate hostile troops along the way and drop down to a new platform. Approach the pods and choose a HIKER or a machine gun. Leave the grenade launcher for later.
The device itself is being guarded by other soldiers, however you'll have to be ready to destroy a new Polycraft as well. Your newly acquired machine gun should do the trick as long as you avoid missiles being fired by the Polycraft. Secure the area and use your bionic arm to destroy a control panel. Watch a short cut-scene, informing you about your success.
It would now be a good idea to return to the pods in order to collect a grenade launcher. There are two more panels for you to destroy and in both cases aside from standard guards you'll also be dealing with Biomechs. Make sure to use the grenade launcher or normal grenades to destroy all the mechs.
Destroying all three panels will allow you to proceed to the bossfight. Return to the area where you've started exploring the Constructor. Notice that you can now head towards a landing pad. Watch a cut-scene upon your arrival, informing you that you'll have to defeat Groeder in order to advance to the next level.
Let's start off by saying a few things about the possible ways of the boss attacking your character. Thankfully his moves can be easily avoided. During the first phase he'll mostly try to jump. The idea here is to force Spencer to jump before Groeder touches the ground, so you won't be affected by his shockwave.
The second of Groeder's attack is a dashing sprint. You can prepare yourself for this attack when you notice a red fog gathering around the boss. All you have to do here is to perform a dodge move by pressing the LB button and by turning the left analog stick to either left or right.
In both cases you should notice that after the attack Groeder needs a moment to rest and that you can see his back. This is your opportunity to perform a counterattack by grabbing him with your hook and performing a zip kick.
Watch out, because after Groeder loses about a half of his energy new drones will show up near the helipad. You don't have to destroy the drones. Instead keep running, so you won't become an easy target for them. Keep attacking the boss with your zip kick moves and eventually he'll die. Watch a new cut-scene.
