Broken but it works, it's possible if your patient enough.
So much so I actually managed to achieve the Platinum trophy for the PS3. The easiest way to do this is to do the online trophies first, the Originality trophy is a nightmare, I had to sit with my Purna game loaded then get to the Lifeguard Station and open up the lobby, and then simply keep refreshing until a suitable match came up. It took a while but I eventually got it, only to be kicked for having no mic, not that I care I was only there for that trophy. Once you have done these 4 I suggest to turn off the network capabilities, it makes the game harder and requires a little more patience but it will reduce the majority of trophies from "glitching" I don't know why it fixes this but it does. I found some trophies were taking upwards of an hour to unlock after I had attained the necessary requirements for them. Turn PSN off and they pop almost instantly.
The game is visually stunning; some of the views are simply spectacular. Especially under High Definition and Techland and Deep Silver went to town on making the Island of Banoi almost real to ones imagination, you see the island and you want to be there, (at least until you run into the zombie hoard) the zombies are intuitive and this makes them not so easy to put down, with various types from slow shambling Walkers to the fast and deadly Butchers of the Jungle. These are then backed by vomit spewing floaters, and the going to crush you in an instant straight jacketed Rams. And as if that isn't bad enough you have human elements who won't simply stand there and let you slice them up, they will hide in cover and open up with various guns and rifles. The game will always provide a challenge.
As you battle through the four key areas of Banoi from the beautiful beach side resort, to the dilapidated and run down city, then you entire the lush and deadly jungle before heading off to the international prison of the island. You will find visuals stunning and challenges to keep your heart and mind racing. Before, you can finally confront the mastermind of your whole ordeal.
I find the quickest and easiest way of dealing with White is to use the battle before hand to charge your rage meter then, when you take on White simply unleash and unload to end the battle rather unspectacularly, it is anti climatic but it saves time and unnecessary deaths.
But seriously considering this is the companies first attempt at FPS gaming and they built the Chrome 5 engine from the ground up they were bound to make a few mistakes, some which they fixed in various patches and others not so much, when the game works it works well and the 4-way drop in drop out co-op was new introduced by them. They had many elements that had to be dropped from the game just to get it to work, including separate stories for each of the main 4. Apparently it got too complex and they had to cut it down in the interest of time and size. And if you can look past the games broken bits it is a damn fine game, and the 4-way co-op is a nice concept if it works ok for you, but to un-glitch the trophies you need to play the single player trophies alone, I know this works as I have platted the game myself. Plus going it alone makes it just that little bit more fun.
