!!!HOPE I HELPED!!!

To do this just pull out the striker shotgun, aim then before the laser comes out press start and choose a different weapon. The glitch lets you run faster, shoot faster, and slice/dice with your knife faster. The glitch will end if you kick, suplex, dodge, get hurt, or go through doors.

To kill Las Plagas carrying chainsaws, use a high strength sniper to keep them stumbling even when they get close, never turn away from them.

There is many other ways but I find this the easiest.

On the 5th chapter, mercenaries mode, or separate ways, there is a big soldier carrying a big Gatling gun named J.J. You can use him to use your advantage to help you out. His bullets, will not only hurt you, but the other Ganados' as well.

The bullets kill them in one hit. So when your surrounded by a lot of people, get in front of them, and if J.J. is nearby he'll blast them all for you. And the best part is that in Mercenaries mode, even when he kills his teammates, it'll still count towards a kill for you.

Hope this helps!

I was surprised I didn't see this on here, but It's not, so I decided to add it. First buy the Stinger Shotgun.

Then pull it out, and aim it but right before the red dot appears press start, and switch to a different weapon. Now Leon should walk/run faster, knife faster. Shoot faster, etc.

I think the effect ends when you go into a door, and go into another level, or when you press start again.

complete the game on easy to unlock infinate rocket launcher and the matilda (revolver) once you complete the game go on extras and complete assignment ada to unlock the chigago typewriter (tommy gun infinate ammo) but it is only in seperate ways in extras so you complete seperate ways to ulock it in the main game

Leon showingoff
When leon is in his gangster gear equip the chigago typwriter and reload he will do a little action with his hat if you do this 3 or 4 times he will throw his hat in to the air and knell down and catch it

If you want to save ammo ( this works great for professional mode), here's what you do: when fighting regular gonadoes shoot them in the leg, then kick them to the ground (if their not already laying down), now knife them while their down.
Done correctly and you can save alot of ammo you'll need later for the big mobs and bosses.

Leave Ashlay behind zombie proof place & fight with zombies & then call her

When a Plagus explodes from the head of the people, use a flash grenade and it will die immidiatly.

When the villager enters the room with the large executioners axe quickly tap L1 and R1.

To save ammo when killing single small enimies shoot the legs till they fall down then slash them w/ your knife. Also shoot them in the head and kick them. It simple.
