Killzone 2 and Halo Wars demos face-off

PSN and Live tussle over biggies

With a boring January now well and truly behind us we look ahead to some February's releases with optimism; Sony and Microsoft going head-to-head with two of their biggest 2009 releases.

In anticipation of Halo Wars' debut later this month, Microsoft today pump a new demo of Ensemble's farewell RTS onto Xbox Live. Its available now, and it weights in at 1Gb.

But wait. Sony aren't finished yet, the platform holder facing-off with a demo of Killzone 2 on the PSN; 1207Mb in size.

The European demo of Sony's much vaunted FPS will allow players to test out the game's opening two sections - and once again comes ahead of a launch later this month.
