- Hidden characters (demo version)
To unlock the Berserker and Commando character in the demo version, make sure that you are not logged onto Xbox Live. Change the year in your system settings to 2009. This will automatically unlock the extra two characters for you to play in the demo. Notice: If you are logged onto Xbox Live, the service will automatically update the date and time on your machine, and this trick will not work.

- Duplicate items
Go into a trade with a second player. Have player two put in an item or a monetary amount, then have them click the 'Trade' button to highlight it, but do not accept the trade yet. Have player two press Xbox Logo, then push Y. Player two will be asked if they want to go to the Dashboard. Player two should be ready to press A on 'Yes'. Do not finalize the trade unless they are ready to go to the Dashboard. Once player two is ready to go to the Dashboard, finalize the trade. When player two sees the screen change, have them select 'Yes' immediately. If done properly, player two will resume the game and will still have their item or bounty, as will the other player. Notice: This glitch can only be done to items one at a time. Money almost has no limit.

- Easy Epic items
While in Aseir, preferably in Co-op mode, go to the mission selection screen, and choose mission 3-4. Go through this mission until you reach a bridge with two enemies you must kill. After this, you will go through one more door where you will kill a troll, a spider, and then another troll. At the location of the last troll, there will be a door in front of you and a pathway to your left which leads to a well. From here, walk through the door, and have another player stand by the pathway. Walk through and kill all the enemies, including the spider. Once they are all dead, have the other player walk across the path towards the hallucination well. Doing this will respawn you back to the path where your friend is located. You may go through the door once more to kill all the enemies. You can do this as many times as desired. To do this while not in Co-op mode, follow all the steps previously described, except you must stand in front of the door so it stays open. You must then shoot all the enemies including the spider. Once they are all dead, go to the exact pathway previously described. You will return to the door, and all enemies will respawn. Doing this long enough will result in an Epic item. Notice: After doing this many times, if the spider does not drop any Epic or Red items, return to Asier to reset the random drop generator to give you a better chance of finding those items.
