Normally this is where I'd write a great big harumph about being ripped off for downloadable content that should have been part of the game all along. Because that's one way to look at the new Versus mode for Resident Evil 5, available as a five dollar download. Versus mode contains no new "stuff". Everything it uses is already in the game: the characters, the maps, the networking code, the weapons, even the scoring system. It's simply arranged in such a way that there are two new modes. It's a bit like the difference between a tostada and a taco. But whereas games like Halo and Call of Duty give you lots of opportunities to change how the game plays online by flipping various settings, Resident Evil 5 charges you money for a couple of preset options.
But instead of harumphing — which plenty of other people are doing just fine so I'll leave them to it — I'm going to describe exactly what you get in Versus mode and tell you whether it's worth it.
