As an atmospheric FPS that does more than enable you to 'pwn n00bz', BioShock 2 is an achievement. It at least attempts to indulge in A-Level philosophy while retaining atmosphere and tension. The Splicers provide a sense of dread as well as humour. The other characters are slightly less well realised. Combat is elegant. Selection of materials provides that RPG element. Poor audio, dull music, illogical health/Eve selection, inconsistent, occasionally unresponsive weapon selection, serve to take it from game-changer to well above-average video game.
