To unlock the swordfight, follow these steps. Open the Hacking program from the main menu. Open a file that has the game completed. Note: You must have completed the game first in order for this cheat to work; and the game file you select at the Hacking menu must have the game completed. Type LOGIN and press Enter. Type GUEST and press Enter. Type DIR, then a space. DIR should now appear in your command list. Access the B Drive through the DIR command. Select TOOLS from the B Drive. It will be locked and will ask you for an access code. The access code consists of 1s and 0s. You must guess the access code, as it is different each time. It is only five digits long. Once you have access to the TOOLS on the B Drive, type all the .EXE files (without the .EXE after them). For example, type DECODE then a space. DECODE will now appear in the command list. Repeat this for all other .EXE files in the TOOLS folder in the B Drive. Now, access VIRTUAL on your command list. Type in FROZENFISH as the password. An authentication test will start. An image of a Chinese symbol will appear, but it will be scrambled. The image is broken into 9 squares, and each square will have five different choices. You must change all the pieces so that a complete image appears. You have a limited amount of time to do this. Once you guess a correct image, the timer will stop and you will be taken back to the hacking screen. Look at the top of the screen. If it says "Solution: Blue", then the line will be traced and you will have to enter TRACEKILL and then press enter as fast as possible or all progress will be lost. Once you enter TRACEKILL, you will have to start back at accessing VIRTUAL on your command list. However, if it says "Solution: Red", then you will hear a message from Neo and get access to the V Drive. Open the V Drive and get all the commands from the TOOLS folder on your command list. Open the ROOTSEARCH program. Now, open the ROOT folder in the B Drive and get the two commands there on your command list. Enter the MAIL command and type THISISNOTREAL as the password and type YES.
You will get a list of phone numbers:
0019495550112
0017145550187
0012135550142
0013105550111
0019495550101
Select the DIAL command and dial 001949555010. You should get a message from Persephone. Next dial 0013105550111. You will get you a message from Trinity. She will give you a number. Select PORTKEY and enter the number. She will start to talk to you. Type NO to both questions and she will give you a program called CRACK on your command list. Open it, then type 8RAM. It should look like this: "CRACK 8RAM". You now have access to the RAM drive. Go to DIR on your command list and access the RAM drive. A list of folder names will appear. Open the TRINITY folder. Get the Training command on your DIR by typing TRAINING then a space. Go to your command list and select TRAINING. On you command list, a file called SWORD.DSK will come up. Select it. It has now uploaded the sword onto you character in the Matrix. Quit the hacking program and select "Save Progress". You can use the sword when you start that game file. It can be used in any stage, but will only a[[ear when fighting enemies by pressing Punch + Kick. You have to enter it again when you turn off the game. Go to the Hacking program, select that file again, select TRAINING, then SWORD.DSK.
Note: There is no need to try to get the blue Chinese character puzzle solution as it does not do anything. you need to get the red solution.
good luck!

also to fight with it press punch and kick at the same time in one player i think it also works in multiplayer you can only take it out when youre near an enemy and your character will do some sort of attack
