A great FPS to have and finish.

Killzone 3 delivers good numbers of different levels with some colorful. The single player mode offers a fun story that makes perfect, it takes only 10 hours to do on Veteran which then unlock the fashion elite who asks him a little more patience and marksmanship, it which will extend the time required to complete the story.
Just like Killzone 2 can then take part of the story to get some trophies or simply internal medals at play. The single player mode gives time event much more fun than Killzone 2 where levels were very similar and where the sets were often dark.
The levels also offer small pilot sessions fun gear armed to the teeth, giving a little more fun in this FPS.
The dialogue and cutscenes are fine, no long waits and no uninteresting words. Sometimes the dialogues are a little less hard for the cinematics, so I happened to not hear what they said, but there is a sub titration is therefore not a problem.

The multiplayer mode offers three game modes, each report are points that will increase your rank and allow you to unlock weapons and skills as professions.J'ai already met this system of professions there a while Enemy Territory on (Quake War) it's great fun as a concept I find and unlock all the weapons and skills levels it will take around 20h see next player level. After there is a lot of medals to get in the game in multiplayer (as Medal of honnor), and for all to have there for a good time (see 50h +).
Another nice side as found in single and multiplayer are put to death in melee, here is the tranche goerge, twists suddenly blindingly obvious with the thumbs or plant the knife in the eye, it tears that ;-)

For platinum trophy, it will take about 30 hours without much focus on them during the game, anyway there is not much, some trophies are very focused and not very interesting to me, it's not like Uncharted 2 or MoH where to achieve big goals.

I much prefer to MoH and graphically puts it a slap in CoD is a very good play.
