Unreal Tournament 3's most eye-catching new feature is a two-metre-square block of pink gelatinous wibble that Epic is currently calling the "slow bubble". Once deployed, it slows the pace of anything that passes through it to a crawl. You can fire a rocket into one end and then run round the side and watch it slowly carve through the centre, before resuming its breakneck pace as it exits. More usefully, you can also dump it in a corridor that chokes your enemy's progress and use it like a flytrap, snaring the opposition and then blasting them at will. And, brilliantly, anybody stuck inside also gets to watch your bullets seep towards them at the same gradual pace that prevents them getting out of the way.
