Are there cheats for resident evil 4 without using a cheat device?

Answer 1

Yes there are several! If you complete the campaign on any difficulty, then you will get 2 costumes. One is a Raccoon City Police Department outfit, and the other is a Black and White outfit. (I don't know the name) Also after you have completed the campaign, there will be 2 new weapons with every merchant, One is a fast-shooting weapon that has unlimited bullets which makes the game much easier, and the other is a rocket launcher with unlimited bullets. Another cheat is that when you are battling Krauser in the campaign, you can defeat him easier if you use your knife. Use your knife to get him on the ground, and then take one of your powerful weapons to, finish him off. At the end of the campaign, you will get a bunch of mini-missions, where you can be Ada Wong. There is also a battle called "Mercenaries" once you have finished the campaign. In mercenaries you can be Leon S. Kennedy, Ada Wong, Jack Krauser, HUNK and Albert Wesker. Hope this does the trick for you!
