Darksiders Cheats

Open Air Parking: This trophy requires you to throw a car at a helicopter in level one. It's essential you remain in regular form and DO NOT transform into demon mode, as you will be unable to throw a vehicle. As soon as you spot the large rock monster in the level, keep an eye out for the helicopter as this is the only place it will appear. Hit the helicopter with the car for the trophy.
High Flier: During the Choking Grounds there are Dark Realm Challenges, one called the Gory End has you fight a large group of bats that you can kill in one hit by using your Sword attack. War will kill the enemy while it's still in the air, allowing you to jump off the enemy towards another bat without hitting the ground. Jump from bat to bat using the one hit kill and you'll be able to score this achievement/trophy.
Devastator: Also in the Choking Grounds is a Dark Realm challenge called Speed Brawl. A large number of weak zombies spawn around you here; use your Blade Geyser once 10 or more have gathered around you and you should easily unlock the achievement/trophy.

In-game, hit pause. Go under the options tab and select enter code.

Here is something I learned how to do which I hope will help those who are unsure as to what to do

When you have to go from the arena and confront the Corrupted Guardian you ride your horse towards the corrupted Guardian shoot at his arm as a stay shot can hit his arm. The Guardian will raise his arm and smash it into the ground which you try and avoid and as his Arm smashes into the ground his arm is vulnerable as a target as the crystals will explode the crystals on his arm you have a got shot at hitting his extended arm which will explode

His arm being extended you will see the yellow explosive crystals and you'll use your gun to try and hit them so that they explode & he collapses to the ground in pieces. Ride your horse to the front of him and look for the glowing Crystal and you & dismount & using your glowing armband and it will pull you to the crystal which will allow you to strike the crystal twice before the Guardian can react.

The Guardian will arise and you’re back on the horse and try avoiding him as he'll try to kill you. You keep moving around him and keep shooting at him and he'll use his left arm to shoot a glowing studded power ball that you have to avoid as it is like a heat seeking missile as it rolls around the ground & Death moves in between the Corrupted guardian legs & the ball will eventually come towards the Guardian and bring him down.

Step 2 _ Once he's down, you move once again to his crumbled form and use your glowing purple arm to go after the first crystal and a few taps and his left arm is now off. With only one arm he only has the right weapon which he'll use to fire the power ball and keep riding around as it will take a few quick moves as the ball will eventually come back and knock the Guardian back to its tumbled form. Located the leg or arm as you'll notice a few ledges with a post and run towards the structure and scale up towards the wooden post.

Once perched on the wooden beam jump towards the crystal & after a few swings of you weapons jump down as the Guardian will once again arise and repeat Step 2 the second position as his power ball will eventually bring him down and you climb up the leg and the second time will bring him down as he stands up and crumbles to the ground.

Now it is just matter of a set scene changes as it is a short scene where Death emerges in the rubble and the one remaining corrupted crystal suddenly comes back to life, but Death simples jumps up and strikes the crystal and...
