How is this a Microsoft Game at all? It was first a mod for Half Life, not a MS product, and then grabbed by Valve and turned into a stand-alone product, again not related to MS. If nobody objects, it should be deleted from this list. — Preceding unsigned comment added by 82.155.57.53 (talk) 16:19, 3 June 2012 (UTC)[reply]
The Xbox version was published by Microsoft. --Mika1h (talk) 22:03, 28 July 2012 (UTC)[reply]
