This game is one of my wanted games recently. But it is not like I'm expected.
Please note that I'm playing XBOX 360 version. Some comment may not suitable for PC version.
Trading is suck.
I expected this game's style is a Nonlinear (Like Fallout 3). But I'm wrong. Players need to follow the chapter and mission (Like most of the FPS games).
It has a trading system for buying and selling guns, ammo, equipment and bullets. I not hate trading. But the game is not Nonlinear. You can't explore the game. And find something to sell. It causes the game get difficult if you can't save ammo in last mission.
Combat is moderate.
There are 7 weapons player can hold in the same time in this game. The weapons slots include 3 guns (Revolver, automatic rifle and heavy weapon), 2 knives (One for melee attack and one for throwing) and 2 "Grenade" (It is just a bomb) (Sticky ones (With nail on it) and non-sticky ones).
Players switch weapons by pressing left or right on the D-pad. Because it just using left and right, the changing weapons is not convenient.
Only 3 weapons can use melee attack, automatic shotgun and both of the knives. Melee attack is difficult to use and useless. So, there is no reason to use melee attack. Even players are out of ammo.
Update: Now with the update on Xbox 360 on 16-th March. There are new options in the controls--The Inventory Type.
It has circular and linear options, The linear option is the old style on changing weapons. The circular option is the new preset for switching weapon easily. Press Y to switch to the knife. Hold Y and move LS to change weapons. The new button style is better than the old one. player can change weapons more convenient and didn't suffer the prepare time on the air gun when switching weapons.
Sneaking around is fun.
There are two type of enemy in the game, human being and mutant moister. Most of the moister is needed to direct fight. But when deal with human, there is always give you a chance to sneak around. In this game, sneaking is always are better. Weapons' ammo is limited in this game. Therefore using throwing knife that can be reuse and saving ammo for the moister is better than wasting bullets.
Story is shallow.
Metro 2033 is base on a novel that has the same name. The story is set after the nuclear-war. This is a good topic for game (In my opinion). But the story is too weak in this game. There is some mystery inside the game is unclear.
