ex. I'm stuck in a room with a box and a gnome. How do I get out?
It seems that Guerrilla Games does not let up on giving gamers what they want, it hasn't been long since map pack #2 was released, and it seems that they do not plan to be going anywhere, and their sticking to their word, making it the best online FPS out there exclusively on the PS3. And now more content is to be released including a new patch (1.28) with much more fixes and improvements to the online experience. Including this will involve maintenance in July 14 (Tuesday) 9am - 11am UK time, oh one more thing, the patch will include two new weapons on the multiplayer experience, the Flamethrower and Boltgun will be included and also lead to more trophy whoring (including myself) for many out there! The maps are expected to be released with the two new weapons on Thursday July 16th, since PSN Store always gets new content that day.
Details on what the patch will include can be found here -> Source
UPDATE: Killzone 2 Map pack #3 will go live on the PSN Store July 23rd
