Yes, the (weapon) damage skills stack according to the author of this popular Steam guide (comments). [...]do any of these skills stack with each other[...]? author: Yes, it should stack accordingly.

Had this issue as well. What worked for me was moving sideways as well for some reason. So during the cinematic as he falls, hold space+S+D, and that may help.

There IS no "suck less at aiming" unlock, or anything of the sort. Sadly, you're stuck to what you have right now. There are some people who prefer using Mouse+Keyboard, due to the aiming reticle being slightly more precise than the aiming laser sight, but either way, skill and getting used to the controls is all you have for this game. If anything, I suggest you try your hand at playing on Amateur difficulty until you feel comfortable with the controls, and then, as you go up through higher difficulties, try switching to spread-fire weapons like machine guns and shotguns.

I'd suggest checking out the C-Virus page on the RE Wikia, as the virus articles are pretty detailed. Here's an excerpt that more directly references what you're asking about, though: Overall, the C-Virus combines the traits and abilities of the two viruses it was derived from, possessing the adaptive mutations of the G-virus and the combustible properties of the T-Veronica virus. The T-Veronica virus is visible in some of the mutations where the mutations usually result in the development of insect-like appendages. The t-Virus can only properly function by consuming the cell in order to produce its energy. This slow breakdown of cells leads to the gradual breakdown of the host, causing necrosis. The virus incorporates itself into the host's DNA, which substantially alters it. This is why creatures, such as bees and spiders, only have very minor mutation, such as increased size, when compared to the human mutation caused by the virus. Within the time frame of an hour, the decayed skeletal and muscular system is reconstructed into a stronger and more durable form. Development can be seen of sharp canine teeth and razor claws, fresh blood seeps into remaining skin giving it a reddish hue, advances in decomposition, and intact eyes become a bright white. Umbrella researchers at the Arklay Laboratory have dubbed this stage "V-ACT", referring to the resulting creature also known as a "Crimson Head". To awaken, the brain must be jolted back to consciousness with a slight but important increase in intelligence, and large increase in agility and aggressiveness. The form the T-Virus takes on depends on the physical state of the host, whether they be living, near dying or dead, and whether they're a human or an animal/insect. The C-Virus uses the T-Veronica virus as a base, so the insect and animal related atributes present in the T-Virus are also found in the C-Virus.

Critical Hits have same meaning as in previous games in RE series, and are powerful attacks that do more damage to enemy and, for some enemies, causes different animation of their death. Note that for most weapons/enemies causing a critical hit requires hitting enemy in special spots of their body, so that will not apply to your every shot (as general gun power upgrade). They help you to conserve ammo with small enemy encounters then you have time for precise shots, but less valuable then confronting large groups of enemies. That's up to you to decide that suits you better.

I realised that once you turn it off, icons that show ammo, skills, and items on the floor will also disappear. Along with that, objective markers disappear such as waypoints to doors, keys and whereabouts of guns to be picked up. However I did realise that herbs always show as a blue marker whether it's on or off. I checked this during a Boss fight so I am not sure if it's limited to that even only. Maybe someone can confirm this for me.

I checked this for myself in the past few days of playing. Skill points are saved even if you play offline.

There are achievements for completing the game in every mode except for No Hope. So completing game on Professional will unlock all of these achievements at once. Number of received skill points is doubled for No Hope difficulty (source). All other unlockables are not related to difficulty setting.

In my experience, quitting a game session at any point before you get the "saving" message in the upper left corner along with the typewriter icon animation means you will not retain any changes to your inventory, or skill points collected. This is not the same as when the "checkpoint" message is displayed, checkpoints DO NOT count as saves.

Camera can't be changed in game for whatever stupid reason. You have to go to main menu and select "camera" from the options. The bottom selections (three of them) deal with depth and the like. You can go to default which is 0 or move it up to 15 the pull the camera back more.

You have limited inventory spaces, ammo takes up space in your inventory like every other item - herbs, grenades, health spray, etc. Each ammo/grenade type can hold up to a maximum amount for each inventory space, afterwards it'll take another inventory space. Check your inventory (Trinagle on PS3, I assume Y on xbox 360) and see if you have any open inventory spaces. If not, you can choose to throw away some uneeded stuff, but try using your inventory before throwing stuff away (for example, combining/equipping herbs, reloading weapons, etc.). While it may seem your current weapon's clip still has space for more ammo, you cant reload directly from an ammo drop, you need to be able to pick it up to your inventory, then reload.

No this is the way they made it which is pretty lame especially on HDtv, but hey you can now run and shoot.

Got to the Playstation store and in the top-right of the main page is a small icon (one of a set of four I think) that is called redeem codes. You can enter the code in here and it will allow you access to a download. Here are some more detailed instructions.

Actually, that is not what it says. If you read it carefully then you will find out that you actually need to press "No" to start with all your previous weapons (I cannot remember the exact text at the moment). I admit I found the text to be a bit misleading too, so I can see how it could easily be overlooked. It's also worth mentioning that replaying the campaign with the "other" character, does not allow use of weapons collected from the first playthrough, ie. you have to collect each characters weapons individually.

Shoot it. Shooting Serpent Emblems unlocks collectibles (files and figures).

You can store up to 17 tablets at one time - the game will not allow you to add more unless you are at 11 (stored) or under.

There is a full list of all skills here. Which appear to have much better description include actual percentage values. This list also says that melee skill increase weapons such as knife and stun rod (not mentioning kicking power) but I assume does include Jake's hand-to-hand combat 'weapon'. It also hints that "Defense" includes all damage, not just from firearms. I didn't create this list so I don't know where these values came from, but the seem pretty logical to me.

As Domescoper has already mentioned, completing all campaigns unlocks the infinite ammo skills for each weapon. The other skills that are unlocked by getting a certain number of kills with each weapon are master skills for that weapon, for example you can unlock "Handgun Master". Each of these master skills increase the damage dealt by that particular weapon. A full list of skills including the infinite ammo and master skills can be found here.

It only counts as a death for you, if the character you play dies in the short death cutscene. If the other character dies (bot or player controlled), it will count to the death of your partner. This makes sense in the way, that you cannot be hold responsible for the inability of your coop-partner. On the other hand, it is ridicoulous, seeing as the survival of your partner depends on your actions in some sequences.

While I do not own the game, someone took the time to upload a set of videos where they play through chapter 1 on professional (so they have a bunch of things unlocked, making everything much easier). If you look at these three videos, you can see them attain an S rank on that chapter, with relevant tips. The important bit, though, is probably this: While the above aren't necessarily the minimum criteria for an S rank, you will definitely attain one if you are at least that good (on that specific chapter, it obviously makes sense that the criteria are different for different chapters).
