Former Producer of Killzone: Liberation and now Test Lead/QA Manager for Guerrilla Games Sebastian Downie recently sat down with website Killzone Unit in an interview about the success of Killzone on both handheld and console, and what the PS3 sequel to the PlayStation 2 FPS is all about. We give you the skinny on all things Killzone.

In the interview, Sebastian Downie talks about the difference between Killzone for the PSP and Killzone for the PS2 - one major difference being that the switch from first person to an isometric gameplay view. He explains that the change was necessary to give the game a pick-up-and-play aspect, for those of us who pull out our handhelds during daily commute or while going number two. He also points out that the camera angle gave players a peek of what lies beyond their characters, which in turn allows them to plan ahead in terms of strategy.

When asked if players should look forward to more downloadable patches and content for Liberation, Sebastian replied with a firm no, stating the difficulty of a company running a development team to make free patches month after month - it would drain the company as a whole. Another reason is that the whole team is now preoccupied with developing a PS3 game, there wouldn't be enough manpower to go around.

Finally, when pressed for more info about Killzone for the PS3, Sebastian Downie merely restated what we all already know: that it's going to be an FPS, and there's going to be a Public Beta later in the year. Other than that, he kept mum, and we can't blame him - Killzone 3 for the PS3 is definitely going to be big.

Updates as we get them. In the meantime, you can check out the full interview at the read link below.
