One of them is a free game, 2010's shooter Metro 2033. The other freebie is especially nice. Pre-orders of Homefront via Onlive will also get a free Microconsole to experience OnLive's service on your TV. That's a $99 value. It sounds like OnLive is expecting a lot of orders from this as the offer is only "when supplies last."
