Personally I really enjoyed the open beta even though it was only one map put on repeat, I still managed to get to around level 15
. From what the story mode has shown it looks like it will be great just like Killzone 2, most of the reason i played Killzone 2 was the story.They have made an improvement on the clunky controls that Killzone 2 had but have still maintained that sprinting motion; also the level up system is much better than before it has gone for a more black ops style system where you choose which guns to buy yourself, but you have to have one type of gun in a class to unlock another (same goes for equipment and role perks)I don't know if anyone else prefers this but I do.
Anyway those are my opinions on the game, I will most likely be getting it and you will probably be able to find me on it a lot.
It's been done.
