There's a lot to be said then for the fact that this near-four-year-old tech can waltz in and still show up nearly every Unreal Engine FPS of the last twelve months. The excellent pacing, unbeatable cast of characters and mental physics puzzles still make for a brilliant experience, and Episode Two doesn't disappoint.
Its cast of characters still beats out anything competing titles offer (though that might be a different story once Mass Effect is out), and fire fights and the AI in general have seen long overdue improvements since the last episode.
Episode Two goes about fixing a lot of the niggling complaints we had about Episode One; after the last instalment's location recycle-fest it's great to finally see some new environments in Half-Life 2. The lush, open forests and rocky hills are a far cry from the blocks of City 17, and it's a real joy to get rough in the jungle.
