Free play
 
 Successfully complete the game with an "A" rank. Enter the options 
 screen and select "House Of The Dead 3". You can now increase the 
 credits past nine until "Free Play" appears. Alternately, play well 
 and get better than an "A" rank one or more times during the game 
 at the point where you lose all your credits. This works best in 
 one player mode.
 
 
 
 Extra items in original mode
 
 Successfully complete House Of The Dead 3, then go to House Of The 
 Dead 2. You will take an elevator down to House of The Dead 2. On

 enemies as quickly and as accurately as possible to get items for 
 original mode in House Of The Dead 2. Complete House Of The Dead 
 3 again to repeat the process. Every time you do this, you will 
 get new items for original mode. This works best if you have unlocked
