Killzone 3 multiplayer demo for 11am

The multiplayer Killzone 3 demo will launch at 11am tomorrow morning UK time, Sony has announced.

All PlayStation 3 owners will have access to the demo, which was previously exclusive to PlayStation Plus subscribers.

It runs from tomorrow until 15th February, and will offer early access to three online multiplayer modes and one offline mode.

Guerrilla Warfare, which supports 16 players, is a classic Team Deathmatch mode in which you and your teammates must try to kill as many of the opposing team as you can against the clock.

Warzone, which supports 24 players, returns from Killzone 2 offering a round-based multiplayer campaign consisting of five randomly ordered mini-missions.

Operations, which supports 16 players, is a new mode which aims to deliver a more story-based gameplay experience, consisting of a sequence of linear mini-missions.

Finally, Botzone is an offline multiplayer mode "ideal for those looking to get to grips with the controls, the weapons or the map layout before going up against live players". The beta features just one map, the "sprawling asymmetrical" Frozen Dam.

Elsewhere, the European PlayStation Blog confirms the launch of PSP games BlazBlue Calamity Trigger and Lord of Arcana on the PlayStation Store.

The Undergarden, which we had expected to launch today, has been delayed to an unspecified date. "Despite the charming blog entry yesterday the game isn't quite ready to hit the EU digital shelves yet, rest assured it won't be a long wait and you're not going to be short of things to do in the meantime," explained PlayStation's Ross McGrath.

What has launched, however, is Bionic Commando Rearmed 2 (£11.99 / €14.99) and X-Men Arcade (£6.29 / €7.99).
