Its weak link is its unsatisfying no-skill-required combat, which might aim this one just over the head of the average Halo fan. But if you want to get a little fancy, there's a lot of fun to be had with some of the game's more indirect fighting methods. It builds an amazing atmosphere by using terrific graphics and sound to set a creepy mood. But BioShock's real strengths are as a compelling work of interactive fiction, and as a unique ride through a warped world with some great payoff built into its mysterious plot. If that description has you even the least bit interested, you won't be disappointed one bit.
