The resident evil 5 on xbox 360 is the only version of the resident evil games I have actually played, so I can't comment on its differences between the series or how well the game has been improved.
This game, along with call of duty has to be my most favourite of all time.

***About the game***

The game can be played in two player on one screen or online using Xbox live.
I play this game on one huge TV with two player and although the screen usage drops dramatically, I still find it OK to play. However I probably wouldn't recommend using two player on a small TV as it may be harder to see and concentrate.
I have played using both the one and two player mode and find the two player mode is a lot easier. When playing together, you can use your teamwork and communication skills to get around and share items as well as discuss how you are each going to work together to complete the level. I also enjoy the competitive side to the two player mode as the scores are showed after each level showing how each player did, it is always fun to compare accuracy and enemies killed.

The game consists of two characters, Sheva and Chris. The two travel through the village which has been infected by a virus turning the residents into what I call zombies. The Zombies are mostly all the same strength in terms of how hard they are defeat although there are the odd few 'big baddies' which take a few more beatings to kill.
The objective of each level is to destroy the larger enemy to succeed onto the next level to eventually come face to face with the master of the virus and destroy him.

The levels differ in terms of their settings, the first level includes a lot of fighting and killing and is one of my favourite levels to return to. Whereas there are other levels which includes using your brain and picking up gems with not many killing to be done.
There are various gems and items to collect throughout the game which can be kept or sold for money. Gold can be picked up by shooting or stabbing to smash open various objects such as crates, the gold is automatically stored into your inventory and turned into money for you to spend.
The great thing about this game is that when you are playing in two player mode, all of the gold is spread between the two players. For example is Chris picks up a 100G pack, each player receives 100 gold to spend.

The weapons are great, there's a wide selection most of which can be updated at a price. The amount of bullets a gun can hold at one time can be expanded along with the impact a bullet makes. Once a gun of your choice has been updated to its maximum, you can go back to the menu and unlock the unlimited ammo for that gun.
To do this, you need to buy to unlock the unlimited ammo using points you receive after completing each level. The amount of points you receive depends on how well you did after each level. This is dependant upon your accuracy whilst shooting, the amount of enemies you killed, the amount of deaths you had and the length of time it took to complete the game.

Throughout the game, ammo can be picked up and is widely available. You find the ammo generally randomly sat around or in boxes which you break open.
Health sticks and health spray can also be found and kept for when needed.
Health sticks can be found as herbs and are found in either red or green. A red cannot be used alone and must be combined with a green herb stick which gives a larger healing effect. Two greens can also be combined together which also gives a larger healing, although a single green can be used alone.

When using health sticks or health spray, if you are within a close range of the other player when in two player mode, the healing with be shared between the two characters although I have found this doesn't change the amount of health you receive.
If a player becomes low on health through an attack or being hurt in some way, the other player usually has a chance to revive the other. If the person reviving has a health stick or spray on them, this will be used at this time. If there isn't any health item available to use, the player will be revived but will be low on health until they use a health item.

The levels can be played in three different ways;
Easy
Normal
Veteran

I have completed the game in Normal mode with my partner and found it the best mode to play in when new to the game. It provides a challenge without being impossible or too easy.
Once you have unlocked unlimited ammo on a gun or a few guns, the game becomes a lot easier as you will be using an updated gun without having to keep stopping to collect or put ammo into your gun.
I now have unlimited ammo on my updated magnum gun which is fantastic, every enemy dies with one shot and the 'big baddies' which used to take what seems like hundreds of bullets now go down with a few shots.

This game is marked an 18 as it contains blood and gore, however I personally don't think the game is all that 'gory'. The blood doesn't come in huge masses and doesn't 'squirt' out dramatically or exaggerated as I have seen on other games.

The graphics on this game are fantastic. Even on a 50 inch TV which I play it on, the image is fantastic and there is quality and effort put into every bit of detail on every level. I tend to wander around randomly when playing and find all sorts of fasinating features such as spides crawling up walls and chickens, rats and snakes on the ground.

The sound quality is also fantastic. We like to play the game with the volume up loud and even without any sort of surround sound speakers, the sound effects from the game draw you in. Each gun has a different sound from it and so it is easy to tell which sound is being made by each character.
Without the gun sounds, its easy to hear the sounds of the footsteps, snake's whisper and the sound of the birds in the sky.
The music appearing when danger is around really puts you into the game and gets your heart racing.

**Price**

This game can now be found very cheap. I bought the game myself after playing it for months at my partners house and found it for a fantastic price of £5 from Cex- a second hand store.
To buy the game new now, it can be found for ;
£11 at play.com
£12 from Amazon
£11.98 from Game
£14.91 from Asda
£17 from Tesco (Online)

I would recommend buying this game second hand as I have seen it is a lot cheaper, and you don't loose anything buying it second hand.

Overall, this is a great game! It has provided hours of entertainment for me and my partner. We have completed the game many times over and are still playing it now.

Thankyou for reading, I also post on Ciao
