Play as Same Character

This is a trick to let you play as the same character on Multi-play . First , on the multi-play screen , put the players on 4, then select the character you want to "multiply" as the fourth player ; select any others for the other players .

Second , on the multi-player screen , put it on 3 players . Then select the same character you chose as the fourth player on the third player's character ; select any players for 1 and 2.

Third, on the multi-player screen , put the game on 2 players and do the routine over as either 1st or 2nd player . Then simply put the game back on 4 players and begin !

Little things you might not know ...

You can cycle through your weapons , backwards, by pressing A and Z at the same time .

Pistols are more accurate though they fire slower than automatics ; automatics miss their targets alot.

Well , thats all I have for right now , if you have any you might like to add please share them with me at [email protected] !
