Duel mode: High score:
The best way to get a high score is to choose one weapon and kill the Boss as fast as possible. It also helps if you collect ammunition for your weapons before defeating the Boss. The shorter the time and more ammunition you carry, the higher the score. You will not lose points for damage or using your medical items.

Deflecting bullets:
If you have the Single Action Army revolver and are being shot at, press R3 to twirl the gun and the bullets will not hit you.

How to beat The End:
When you first start to fight him, go into one of the other two areas and not the original one you start in. Run around and roll to dodge his bullets. When he shoots at you, press Start and select "Map". One of the sniping locations will be highlighted in red to show you where he is at. This is assuming that you have uncovered the entire area. To remove the tranquilizer darts from where The End shot you, press Start and select "Cure". Select the Knife to remove the tranquilizer darts. Do this as soon as possible to avoid losing stamina.
