Halo Wars is rumoured to be Microsoft's next full-bloodied first-party game to support cross-platform play between PC and Xbox 360. According to rumour circulating, a PC version of the RTS is going to be announced at next month's GDC in San Francisco. To be honest, we wouldn't be at all surprised if Halo Wars was confirmed for PC at some point. Previous games in the Halo franchise have appeared on the platform, after all. Though this is a slightly different kettle of fish.
We reached for the Microsoft hotline... "We do not comment on rumour and speculation", the company's UK arm replied when we queried it on the report. Cross-platform action between PC and Xbox 360 has hardly set the world on fire to date. Shadowrun failed to impress, and we've heard pretty much zero in terms of support from third-parties, although Sega RTS Universe at War does have the feature.
Halo Wars is in development at Ensemble Studios, which has worked on the Age of series of strategy games for PC. And it's looking ace.
