Deadpool Walkthrough Part 4 – Job One (GWN Building: Rooftop)
Start on over to the left. There is a soldier ahead with his back to you. Sneak up on him and execute him. Just go on forward from there. Go to the left of the stairs first to find more DP Points. After that go on up the stairs and continue forward. Break off over to the left and deal with the soldiers there. Fight your way over to back right. There are 2 soldiers on a shack above you. Gun them down, go over to the vents you see by the building, jump up onto them and from there onto the shack. Cross over and drop down to make it a bit closer to the helicopter.
As soon as Deadpool lands there are more soldiers to deal with. This time they found the “On” switch for the helicopter and are using it against Deadpool. Shoot at it for a while and it is revealed you cannot shoot the helicopter down (or the people inside it) but you can scare them using your guns. Shoot at the helicopter to get it to lift away for a moment to give you time to move. Drop down to the area below and go over to the right. Kill off the 2 Soldiers who start shooting at Deadpool and then climb up to where they were. Once again shoot the helicopter to give yourself more time. Drop down into the lower area, go over to the right and be wary. As you move forward, from the left, 2 soldiers will start shooting at you. Take them out and then head to where they were. Go around the corner and now it is getting close to a run up to the helicopter.
The Voices complain about the DT 1981s sucking compared to the Gatling gun on the helicopter. Time to fix that. Move over to the left and take cover behind the venting. Shoot at the helicopter then make a run for the helipad, shooting at the chopper. Once underneath the pad, look between the strut and the controls to find some DP Points. Now head for the stairs on the other side of the strut. From there just run up the helicopter and hijack it.
Deadpool now has a minigun. Just push down the trigger and hold it. Watch the combo build and the kill count soar for a while. Listen to Deadpool as best you can to kill as many of the soldiers as possible. Until you get shot down you have infinite ammo so do not worry about missing or anything like that. Just shoot and watch the meat fly.
After the carnage finishes and Deadpool has hauled himself into the fancy room take some time to get new weapons and upgrade what you can. From there set into the henchmen that still have not learned and take them all out in the flurry of blades, bullets and explosives. There are about a dozen to kill to take your time.
After the henchmen go down a new enemy is thrown at you. This fellow has a massive RPG that he will readily and frequently fire. It is best not to engage in melee but instead run around and unload your various guns at him (mines, bear traps or grenades are also a good idea). Whenever this foe fires his RPG at Deadpool: Teleport. This will make sure you do not take any damage from it. Run around through the corridors and use as much cover as you can against this foe.
When you do take him down head over to the rocket launcher and grab it. Use it against the second round of soldiers and second guy with “The Solution” that you need to deal with. After that just enjoy the cutscene that ends the chapter.
