A bunch of hands-on impressions have cropped up for this today, and..it actually sounds very promising.

And then there's multiplayer. First off, it's fun. It's really, really fun. Liberation includes the basic stuff, including deathmatch and team deathmatch. But it also includes a "last man standing" mode, where players kill each other until only one survives. There's even an objective mode, which should see groups of soldiers storming enemy installations, destroying targets and the like. But as far as regular old deathmatch is concerned, it's fast, fun and very rewarding, even at this stage of development.

Regardless, this isn't a run-and-gun shooter, which we learned the hard way after getting shot full of lead at point-blank range a couple of times. Instead, it's important to use cover, flush out entrenched enemies with grenades, and even set up diversionary maneuvers. Complex tactics will probably prove necessary, because the artificial intelligence seems to put on a surprisingly good show. Helghast soldiers will use cover and flank you if you're getting too comfortable behind a barrier. Destructible objects in environments also mean you won't be able to hide forever. Various context-sensitive actions are also possible, such as delivering a knockout blow against close-range combatants, or using various objects in the environment, such as mounted guns. We got to try several different single-player missions, and each of them seemed challenging and varied on first impression.

So for Killzone: Liberation, the developers came up with the idea of extending the Killzone gameplay to an overhead, semi-old school perspective. Players will still be running around shooting at people (and each other), but they'll be doing so with a drastically different camera and control scheme.
Of course, this kind of shift comes with a few other gameplay changes. Grenades, for instance, are handled by holding down a button and moving a dashed line around to determine where you want to throw them. Also, a duck maneuver plays a key role in your defense against enemies, since you can shoot over a target in front of you with a special animation while ducking.
