If you're a rabid fan of the series, the "Lost Frontier" title might sound familiar to you. Way back in 2006, Sony patented the moniker with the description of a "real-time online networked game," but it would appear that initial idea fell through. See, Lost Frontier on the PSP and PlayStation 2 is a strictly single-player affair that picks up shortly after Jak 3 while focusing on platforming, combat, and vehicles. Keira has set out on a spirit quest and the boys are trying to figure out what is behind the world' sudden eco shortage. The journey will take the trio to "the Brink" of the universe -- the very place the Precursors didn't get around to finishing -- so expect jagged rocks and cliffs that lead to nothingness.
