Lacks of many things, however it's a well improved version of other resident evil series!
About the game itself, it has 5 scenarios. All of them have many things to discover, but they are kinda small. You will have the possibility to chose from 8 characters, each of them with different status (speed, HP, virus gauge, special abilities..) and lots of NPCs that you can unlock by beating some goals.
The virus gauge is a new addition to the series. Now you won't die by taking a lot of damage. Instead you will fall on the floor and a gauge meter will grow really quickly until it reaches 100%. When it does, Game Over. The gauge also grows when you are just Fine, but much slowly. This gauge addition doesn't make any sense.
You will have 2 partners fighting along with you. Up from Normal to Very Hard difficulties they will just become a burden. Instead of having to heal one person, you'll need to take of 3. Partners also tend to waste a lot of the available Medicine, specially female one's. Except for one or 2 characters, they are worth nothing. They don't fight very well. They just ram themselves into the enemies, trying to complicate your life.
Multiplayer is a great addition to the series available in the NA versions. Though with the lack of communication options available, I doubt it will be a very rich experience - maybe a dull one.
The best part of the game is probably the sort of RPG features. Each character has a certain speed. Slower characters can't run from enemies while fast ones dodge them easily. Each character also has HP - Hit Points. HP is something crucial. Although the medicine available hinders its impacts. All medicine heals a certain amount of HP rather than a % of the characters HP. A Green Herb (recovery Medicine) heals 500 HP. The maximum HP a character can have is 4000. If you divide the characters HP by 4, you will obtain its current status. These are: Fine and Caution yellow and orange - your character can run better than ever; Danger - your character can't run and walks very slowly. This means 2 green Herbs are not enough to make a 4000 HP character recover from danger, while a single herb is more than enough to recover a 1500 HP character from danger.
Each character also has a certain and fixed virus gauge growth. This doesn't affect anything if you don't plan on getting hit a lot.
Each player comes with a special ability too. From opening locked doors and lockers to dodging enemies attacks or kicking them.
So while these additions might seem fun, all the horror was removed from the game. The game seemed more like a kids game. Nothing was scary...it just seemed like a RPG with ugly monsters - a bad one.
However, it's still a nice addition to the series and hopefully future releases will try to focus on the Action rather than the RPG part. I mean, this is supposed to be a survival horror game after all.
