While I thought
Killzone 2 was graphically well done, I found the gameplay lacking and got a little bored halfway into the game. Don't even get me started on the end fight with Radec. In any case, the guys at Guerrilla Games thought the same thing about variety in the game as well.
Producer Steven Ter Heide
has gone on to say that more variety will come in
Killzone 3. From the sounds of it, it looks like the company's going to be trying to add a lot of new little gameplay aspects early on rather than save it more towards the end like in the second game. Let's hope that what he describes in one level can translate to the entire game.
