RESIDENT EVIL 5

Professional difficulty can be unlocked by beating the game on Veteran. You can also attempt it on your first playthrough by joining a co-op partner who has unlocked Professional (Thanks Terminator!), however, this is not recommended due to the lack of unlimited ammo. All difficulty trophies stack.

On professional difficulty, one hit from almost everything will send you into dying status and you will bleed out very quickly. The real difficulty for this trophy comes from the AI you need to protect whom will rarely return the favour. The majority of the time while you're bleeding out, they either won't make it in time or will just stand there watching you die. Finding a competent partner will eliminate this problem: Co-op Partners Thread.

A bulletproof vest can be purchased for both characters in the store for $10,000 a piece which can prove vital in the later chapters. A melee vest can be worn with it for the same price, but I found it pretty useless. Infinite ammo will be critical to a successful professional completion. There are a few requirements that must be met before you can obtain infinite ammo:

• Complete the game
• Fully upgrade the weapon you want to add infinite ammo to
• Purchase infinite ammo for that weapon in the bonus settings menu. It requires exchange points acquired throughout the story, not cash
• Turn infinite ammo on in the special settings menu.

The Grenade Launcher cannot be upgraded and thus infinite ammo cannot be used. Despite not being able to upgrade the rocket launcher either, you can unlock infinite ammo for it by having an overall completion time of under five hours. In many levels you can avoid the majority of encounters and just run past everything cutting down your time significantly. You can view your completion time for each chapter along with your total completion at the chapter select screen. 1-1, 1-2, 2-1, 2-2, 2-3 and 5-1 are all quick levels that can be completed in 5-10 minutes. Focus on getting those out of the way first, an infinite weapon will further help with this. If your time is still over five hours, try tackling 5-3. You'll likely be able to complete it in half of your original time.

Before starting the first chapter you'll want to give your partner an infinite weapon preferably a magnum or they will be completely ineffective. A second infinite infinite weapon for yourself for any close range battles would also be helpful, but it is by no means necessary. If you're interested in how the AI will act with different weapons, BerserkerBR has compiled a guide for it here.

I would recommended playing as Sheva throughout this playthrough for a few reasons. 1 - The turret that she uses throughout chapter 2-3 is superior to Chris'. 2 - You'll be the one hoisted into areas where only you can access instead of having to protect the AI. 3 - With the exception of 4-2, 5-3 and 6-3, Chris' AI is quite capable.


On the higher difficulties there are a couple of differences in the gameplay:

Chainsaw Majini - After killing them keep your guns locked onto their body for a minute as there is a high chance they will awaken. Of the four Chainsaw Majini's I killed on professional, three awakened.

Quick Time Events - These will become more complex. On the raft section on 3-2 you will have to alternate between pressing , and , instead of just pressing , each time. Any QTE prompt that pops up could switch between buttons unlike the sole button on amateur. If you die from a QTE, it may necessarily be the same button once you reach it again. If you're having trouble pressing the right button in time you can try the pause trick - pause the game just before the prompt appears, so that you'll know exactly which to press, no pressure involved.

The two toughest points in the game are without a doubt the battle against Ndesu and the second 'fight' in chapter 5-3. For the battle against Ndesu you'll want to be playing solo as you'll both have to succeed at the QTE which can really screw things up for you. If you fail a single QTE, restart the checkpoint. Barring a complete miracle, you will not be able to survive throughout the rest of the battle. When Ndesu isn't right up close, focus on taking out all but one of the Majini firing at you, especially the Molotov Majini. You will not survive the fight if you leave them all standing.

For the second fight in 5-3 it would probably be better to control Chris since you can distract her by pressing . Always keep a close distance between the two of you or she will get out her machine guns and let loose. It's best to rip the device off solely by tearing while standing and/or shooting at it. If you attempt to tear it off while she's on the ground, you'll have to eventually pass a QTE which will put you in a dying status if you fail. Unless your partner revives you the instant you stand up, you will probably perish.
